The Evaluation Board "EVAL-1EDI20H12AH-SIC" is intended to evaluate the Infineon EiceDRIVERTM 1EDC20H12AH or 1EDI20H12AH together with the Infineon SiC MOSFET IMZ120R045M1 in an application circuit to understand the features and performance of both devices. The board contains two gate drivers to drive two SiC MOSFET switches in half bridge configuration. An additional gate driver is used to transfer the over-current information through the isolation barrier between the power high voltage side to the low voltage input side. Some supporting circuits like voltage regulator and DC-DC converter are implemented for a simple use in the laboratory. The DC-DC converter provides galvanically isolated supply voltages for each SiC MOS driver stage. The picture shows the top view of the EVAL-1EDI20H12AH-SIC. 2 1.0 2017-11-30 Evaluation Board EVAL-1EDI20H12AH-SIC / EVAL-1EDC20H12AH-SIC 1EDI20H12AH/1EDC20H12AH with CoolSiCTM MOSFET IMZ120R045M1 1 Electrical description Figure 1 EVAL-1EDI20H12AH-SIC top view The board has a size of 85 x 55 x 30 mm3. It is intended to be used for so called double pulse testing. However, it's under the responsibility of the user to adapt it for testing it under continuous operation by adding a heat sink. An additional blocking capacitor to the high voltage supply is recommended. The low voltage interface can be controlled by a pulse generator, a microcontroller or other digital circuits. For safe operation a fast overcurrent detection and protection circuit is implemented with a galvanically isolated feedback path to the low voltage input side. The trigger flip-flop is implemented to latch the overcurrent event information. This circuit will report the overcurrent event and turns OFF both drivers after an overcurrent event. The button S1 will reset the flip-flop to enable the drivers again. Further description is provided in the section Overcurrent protection. 1.2 Electrical features 1.2.1 Supply voltage, operating conditions and absolute maximum rating The evaluation board is intended to be used in the laboratory for so called double pulse tests with limited power dissipation. The user has to ensure a stable supply voltage by adding an adequate capacitor. In case of continuous operation, the user has to take care of the cooling of the CoolSiCTM MOSFET IZM120R045M1 by adding adequate heatsinks. The heatsinks should be isolated from each other by using a separate heatsink for each transistor. The heatsinks should have a safe distance to the capacitors C5 and C13 to avoid arching due to high voltage. 3 1.0 2017-11-30 Evaluation Board EVAL-1EDI20H12AH-SIC / EVAL-1EDC20H12AH-SIC 1EDI20H12AH/1EDC20H12AH with CoolSiCTM MOSFET IMZ120R045M1 1 Electrical description Table 1 Absolute maximum ratings pin name Abs.

Supply +15V at connector J4.1 with +16 V and connect supply GND to connector J4.2 2. The red LED4 will turn ON 3. Push S1 to reset the error flip-flop 4. The red LED4 will turn OFF and yellow LED3 will turn ON 5. Connect the digital driving device to the digital interface connector, labeled CON1: * pin 6 for IN_T * pin 8 for IN_B 6. Connect the high voltage supply to connector J1.1 or J1.2 and HV GND to J3.2. An additional external capacitor > 100 F from J1.1 to J3.2 helps to stabilize the supply voltage. 7. Connect the inductive load to J2.1. The other side of the load can be connected to different nodes depending on the requirements. Please see Table 4 8. The board is now ready for tests Table 4 Load connection To be tested Connection 1st side of load Connection 2nd side of load Note High side driver TOP J2.1 J3.1 and J3.2 High side operation Low side driver BOTTOM J2.1 J1.1 or J1.2 Low side operation High- and Low side drive J2.1 J2.2 or another gate driver board Half or full bridge operation ENABLE must be pulled down to Low to enable a driver. The different drivers can be turned ON or OFF by driving either IN_T for the High side TOP or IN_B for the Low side BOTTOM driver at the digital interface connector. Only one input signal, either IN_T OR IN_B should be pulled to "High" to avoid turning ON both drivers at the same time. To adapt the circuit to the application requirements, resistor or capacitor values can be changed to optimize the performance. 1.2.3 Overcurrent protection An over current protection is implemented to protect the board and components against high current . 5 1.0 2017-11-30 Evaluation Board EVAL-1EDI20H12AH-SIC / EVAL-1EDC20H12AH-SIC 1EDI20H12AH/1EDC20H12AH with CoolSiCTM MOSFET IMZ120R045M1 1 Electrical description The current is determined by measuring the voltage across the shunt resistor R18. This is available at the two test points TP7 and TP10. The detection circuit measures the voltage across R18, sends the signal through a low pass filter R17 and C21 and compares it to a reference voltage with the comparator IC5. The reference voltage is defined by the voltage divider R11 and R19. The trip point is about 32A and can be adapted to customer requirements by changing R18 and/or adapting the reference voltage divider R11 and R19. The output signal is transferred with IC3 to the low voltage domain to trigger the flip-flop and store the over current event. Once the flip-flop is triggered, it turns off both gate drivers by the ENABLE signal. In addition, it reports the over current event to the digital interface connector as FAULT signal and will turn ON the LED4. To go back to normal operation, S1 needs to be pushed to reset the flip-flop. As feedback, LED4 will turn OFF and LED3 will turn ON. The turn OFF of both drivers due to over current is displayed in the fig. OC Turn OFF and details in fig. OC Turn OFF details. The low side driver with load from switching node to HV supply was used to demonstrate the protection behavior. The HV supply voltage during the test was 530 V. The typical over current turn OFF threshold is about 32 A.

It's typically used to connect to a microcontroller and supplied with VCC1. Every supply pin VCC1 has a blocking capacitor C8 and C18 to GND1. Every gate driver has two inputs: * IN+, non inverted input, high signal will turn the corresponding SiC MOSFET ON. * IN-, inverted input, high signal will turn the corresponding SiC MOSFET OFF. The circuit part on the right hand side of the schematic is the feedback interface to deliver over current signal information to the microcontroller. C2 and C5 are high voltage supply blocking caps. Only C5 is populated, while C2 is optional. J1 is the input connector for the high voltage supply. The connector J2.1 is connected to the center of the half bridge called PHASE. J2.2 is connected to the blocking capacitors C5,C13. C12 and C13 are high voltage supply blocking caps. Only C13 is populated, while C12 is optional. J3.2 is the connector for the high voltage supply ground. J3.1 is the connector to the shunt resistor R18. 2.1.1 High side gate driver TOP In the top center section the high side driver, called TOP, is shown. It's the output of the gate driver IC2, supplied with VCC2_T and VEE2_T. VCC2_T is decoupled by the blocking capacitor C9 and VEE2_T has the blocking capacitor C10. The charging current of the SiC MOSFET T1 is limited by R3. The discharging current of the SiC MOSFET T1 is limited by R5. The capacitor C6 is optional and not populated. It can be used to decrease the switching time of T1 if needed. 2.1.2 Low side gate driver BOTTOM In the lower center of the schematic the low side driver BOTTOM is shown. It's the output of the gate driver IC4, supplied with VCC2_B and VEE2_B. VCC2_B has the blocking capacitor C19 and VEE2_T has the blocking capacitor C20. The charging current of the SiC MOSFET T2 is limited by R10. The discharging current of the SiC MOSFET T2 is limited by R13. The capacitor C14 is optional and not populated. It can be used to decrease the switching time of T2 if needed. The shunt resistor R18 is used to detect over current. The low pass filter R17 and C21 will filter the voltage signal across R18 and deliver it to the comparator IC5. The reference signal for the comparator is created with the voltage divider R11 and R19 with filter capacitor C22. The over current detection threshold can be adjusted by changing the reference voltage with divider R11 and R19 or changing the shunt resistor R18. IC1 is a voltage regulator to create stabilized VCC2_5 out of VCC2_B. VCC2_5 is the supply voltage for IC5 and IC3. LED1 is a signal LED to show that VCC2_5 is available. C1, C3 and C4 are blocking capacitors for proper operation of IC1. IC3 is used as feedback part to transfer the over current information from the HV BOTTOM domain to the low voltage domain. The supply voltage VCC1 is supplied by VCC2_5 and blocked with the capacitor C15. The output side of IC3 is transferring from OUT+ and OUT- through R8 to the base of T6 of the fault flip-flip in the interface schematic. VCC2 of IC3 is supplied with +15V. 10 1.0 2017-11-30 D C B A COFID1 FID1 PID301 COFID2 FID2 COFID3 FID3 SS14-E3/61T PO015V0IN +15V_IN PID302 COD3 D3 PITP1601 PITP1201 +15V 4.7uF 25V COC37 C37 GND COTP16 TP16 PIC3702 PIC3701 COTP12 TP12 PO015V +15V 50V PIC3801 COC38 C38 PIC3802 1uF 50V 50V GND OSC CS PITP1301 COTP13 TP13 LO 4 PIIC704 6 VS PIIC706 7 HO PIIC707 8 VB PIIC708 IR2085SPBF 3 PIIC703 2 PIIC702 COTP15 TP15 1 PIIC701 VCC COIC7 IC7 5 PIIC705 COTP14 TP14 PIC3901 PIC40 1 COC39 COC40 C39 C40 PIC3902 0.001uF PIC40 2 100pF PITP1501 PITP1401 68k COR37 R37 PIR3701 PIR3702 BAT165 PID502 PID501 COD5 D5 ISOLATED POWER SUPPLY PIC3602 PIC3601 COR39 R39 1k COR42 R42 PIR4201 15 PIR4001 COR40 R40 15 PIR3901 COC36 C36 0.1uF 50V PIR4202 PIR4002 PIR3902 3 PIT803 1 PIT801 4 PIR4 01 PIC3401 PIC3402 2 PITR102 25V 25V N1 5 PITR105 4.7uF 25V COC34 C34 PIC4101 PIC4201 COC41 COC42 C41 C42 PIC4102 4.7uF PIC4202 4.7uF BSL306N T8B BSL306N COT8A COT8B T8A COR44 R44 0.22 PIR4 02 PIT802 PIT804 PIT805 PIT806 T60403_F5046-X007 COTR1 TR1 N2PITR108 8 7 PITR107 N3PITR1012 12 11 PITR1011 GALVANIC ISOLATION 5 1.0 2017-11-30 PIC4302 PIR4701 COR47 R47 820 PIR4702 Checked: 03/29/2017 29.03.2017 GCD Drawn: 29.03.2017 PCB-Number: 1.1 14:07:27 PILED601 PILED602 PIR4301 1 PIT1001 0.15 PIT903 0.15 T10 BC857C PIT10 2COT10 PIR4501 PIR4601 PIR4602 GND2_B COR45 R45 100k COR46 R46 PIT10 3 -5V TOP POVCC20B VCC2_B +15V BOTTOM -5V BOTTOM Infineon VEE2_B POVEE20B VEE2_B POGND20B GND2_B High Voltage BOTTOM Domain COLED6 LED6 Green PIR4502 VEE2_T POVEE20T VEE2_T POGND20T GND2_T GALVANIC ISOLATION VCC2_B T9 BC857C PIT902COT9 PIR3501 PIR3601 PIR3602 GND2_T COR35 R35 100k COR36 R36 PIR3502 POVCC20T VCC2_T +15V TOP 8 High Voltage TOP Domain VCC2_T COLED5 LED5 Green COR43 R43 3k65 PIR4302 D10 BZT52C5V6T-7 5.6V PID10 1 COD10 PID10 2 PIR4102 1 PIT901 Engineer: Michael Wendt COC45 C45 4.7uF 25V COC44 C44 4.7uF 25V 0.15 PIR4101 COR41 R41 COR38 R38 820 PIR3801 PIR3802 PID602 PILED502 PILED501 PIR3401 COR34 R34 3k65 PIR3402 D6 BZT52C5V6T-7 5.6V PID601 COD6 Printed: PIC4501 PIC4502 PIC4 01 PIC4 02 COC35 C35 4.7uF 25V COC33 C33 4.7uF 25V PIR3302 1EDI60I12AH - Infineon COD9 D9 BAT165 COD8 D8 BAT165 PIC3501 PIC3502 PIC3 01 PIC3 02 0.15 Date: PID901 PID902 PID801 PID802 COD4 D4 BAT165 COD2 D2 BAT165 COR33 R33 PIR3301 Ver.: COD11 D11 BAT165 4.7uF 25V PIC4301 COC43 C43 COD7 D7 BAT165 PID401 PID402 PID201 PID20 7 Title: PID1 01 PID1 02 PID701 PID702 PIC3202 4.7uF 25V PIC3201 COC32 C32 6 1 2 3 2 3 2 6 5 4 2 11 1 Power supply schematic 2 Figure 5 2 D C B A 2.2 3 1 Evaluation Board EVAL-1EDI20H12AH-SIC / EVAL-1EDC20H12AH-SIC 1EDI20H12AH/1EDC20H12AH with CoolSiCTM MOSFET IMZ120R045M1 2 Schematic Power supply schematic This part explains the schematic of the power supply containing the isolated DC-DC converter Evaluation Board EVAL-1EDI20H12AH-SIC / EVAL-1EDC20H12AH-SIC 1EDI20H12AH/1EDC20H12AH with CoolSiCTM MOSFET IMZ120R045M1 2 Schematic The power supply schematic in Figure 5 is showing the galvanic isolated DC-DC converter to generate the isolated supply VCC2_T and VEE2_T to supply the high side driver and VCC2_B and VEE2_B to supply the low side driver.

The 10 pin interface connector to the digital driving circuit like a microcontroller, the 15 V input connector J4, the reset button S1 and VCC1 output J5 are placed on the lower left side of the schematic marked as connectors. The error flip-flop is displayed on the right hand side with the Status LED. It's triggered with the signal from R8 in the gate driver schematics. LED4 will indicate an over-current event and LED3 will indicate normal operation. The error flip-flop with over current detection circuit is intended to protect the board during lab evaluation. In the real application it's not required. 3 PCB Layout A special PCB layout was developed to demonstrate the excellent performance of the components used. Main part is the interaction between the gate driver and the SiC MOS transistor as well as the current path for the high power supply, load and power GND. Also the supporting circuits like the DC-DC converter, the over current detection with the shunt resistor and the power supply of all circuit parts were optimized for this board. 14 1.0 2017-11-30
