Introduction The purpose of Cree's KIT8020-CRD-5FF0917P-2 evaluation board is to demonstrate high-speed switching performance of Cree's 3rd Generation (C3M) silicon carbide (SiC) Metal Oxide Semiconductor Field-Effect Transistor (MOSFET) in a TO-247-4 package. Cree's new TO-247-4 package provides a separate Kelvin source pin for gate drive signal return which reduces gate ringing and provides clean gate signal. Cree's KIT8020-CRD-5FF0917P-2 evaluation board (as shown in Figure 1) comes in the configuration of a basic half bridge circuit with two Cree SiC MOSFETs (P/N: C3M0075120K). This evaluation board can be configured into synchronous boost, synchronous buck, inverter and other common power conversion topologies. Moreover, this evaluation board is designed to allow a user to: Analyze a printed circuit board (PCB) layout example for driving Cree's generation 3 SiC MOSFET in a newly developed TO-247-4 package. Evaluate the performance of a Cree generation 3 SiC MOSFET in a TO-247-4 package during switching events and steady state operation. Characterize Turn ON (EON) and Turn OFF (EOFF) losses. Measure double pulsed clamped inductive switching data. Evaluate the effects of different gate resistor (Rg) values, uni-polar versus bipolar gate drives, various thermal interface materials and cooling methods. Figure 1.

Comparison between Cree's C3M and C2M SiC MOSFETs The main difference between Cree's generation 3 (C3M) and generation 2 (C2M) SiC MOSFET is the gate to source voltage (VGS) requirements. As shown in Figure 2 and Figure 3, operational values of VGS for C3M are -4V/+15V while operational values of VGS for C2M are -5V/+20V. This reduction in VGS requirements lowers the overall power losses in Cree's C3M SiC MOSFET. Figure 2. VGS requirements of Cree's C2M MOSFET VGS REQUIREMENTS Operational VGS Maximum VGS Safe Operating VGS Figure 3. VGS requirements of Cree's C3M MOSFET C2M MOSFET -5V/+20V -10V/+25V 0V/+18V C3M MOSFET -4V/+15V -8V/19V 0V/+15V Table 1.

Cree, the Cree logo, and Zero Recovery are registered trademarks of Cree, Inc. 8 A general block diagram of Cree's KIT8020-CRD-5FF0917P-2 evaluation board is shown in Figure 5. Besides the two Cree's C3M0075120K SiC MOSFETs (Q1 and Q2) in a half bridge configuration, there are two onboard isolated gate driver circuits which are used to drive both Q1 and Q2, there are four power connectors (CON1, CON2, CON3, and CON4) for connecting to the +DC link, -DC link, and the midpoint, and there is also a 10-pin ribbon cable connector (J10) onboard that carries the logic power and gate drive control signals. CON1 Q2 J10 Gate Drive CON2 Q1 CON3, CON4 Figure 5. Block Diagram of Cree KIT8020-CRD-5FF0917P-2 evaluation board Each gate drive circuit consists of an opto-coupler based isolated gate driver chip from Silicon Laboratories Inc. (P/N: SI8261BCD) and a 2W isolated DC/DC converter from Murata Manufacturing Co. Ltd. (P/N: MEJ2D1209SC). The Silicon Laboratories chip provides 5000V of isolation between the low voltage control side and the high voltage drive side. Each DC/DC converter is sourced with a +12V input. Through a series of jumpers, JM1-JM4, (as shown in Figure 6), each gate driver can be configured as a low cost uni-polar (+15V/0V) gate driver or as a high performance bi-polar gate driver (+15V/-3V). The DC/DC converter provides 5.2 KV maximum isolation for 60 seconds. CPWR-AN20, Rev -, 02-2018 Copyright (c) 2018 Cree, Inc. All rights reserved.

Example Topologies The reason for choosing a half bridge circuit for Cree's KIT8020-CRD-5FF0917P-2 evaluation board is because of its ability to be a constituent portion of various power conversion topologies. Two example configurations are listed below, with the components shown outside of the dotted box. Cree's KIT8020-CRD-5FF0917P-2 evaluation board can also be configured in various other topologies (such as a non-synchronous buck topology) with modifications, and with the addition of multiple evaluation boards one can prototype a H-bridge or a 6-pak based power conversion topology.

Terminals and Connectors CAUTION ***HIGH VOLTAGE RISK*** THERE CAN BE VERY HIGH VOLTAGES PRESENT ON THIS BOARD WHEN CONNECTED TO AN ELECTRICAL SOURCE, AND SOME COMPONENTS ON THIS BOARD CAN REACH TEMPERATURES ABOVE 50 CELSIUS. FURTHER, THESE CONDITIONS WILL CONTINUE AFTER THE ELECTRCIAL SOURCE IS DISCONNECTED UNTIL THE BULK CAPACITORS ARE FULLY DISCHARGED. DO NOT TOUCH THE BOARD WHEN IT IS ENERGIZED AND ALLOW THE BULK CAPACITORS TO COMPLETELY DISCHARGE PRIOR TO HANDLING THE BOARD. The connectors on the board have very high voltage levels present when the board is connected to an electrical source, and thereafter until the bulk capacitors are fully discharged. Please ensure that appropriate safety procedures are followed when working with these connectors as serious injury, including death by electrocution or serious injury by electrical shock or electrical burns, can occur if you do not follow proper safety precautions. When devices are being attached for testing, the board must be disconnected from the electrical source and all bulk capacitors must be fully discharged. After use the board should immediately be disconnected from the electrical source. After disconnection any stored up charge in the bulk capacitors will continue to charge the connectors. Therefore, you must always ensure that all bulk capacitors have completely discharged prior to handling the board. CPWR-AN20, Rev -, 02-2018 Copyright (c) 2018 Cree, Inc. All rights reserved.

Since the heatsink is common to both MOSFETs, it needs to be isolated from each MOSFET tab. This isolation is achieved with the help of a high performance Kapton thermal interface pad manufactured by Fisher Elektronik (P/N: KAP1P). A rendering of the assembly is shown below in Figure 10.

Test Point Locations The test points of Cree's KIT8020-CRD-5FF0917P-2 evaluation board are highlighted in Figure 11. A standard .100" pin header should be soldered on all the major nodes in order to connect oscilloscope probes properly. Figure 11.

Oscilloscope probe attached Figure 12 shows an example in which a pair of 0.100" pin headers are soldered on the test points13 & 14 of Cree's KIT8020-CRD-5FF0917P-2 evaluation board. With the help of these headers, an oscilloscope probe can monitor gate to source voltage (VGS) of the lower MOSFET (as shown in Figure 13). CPWR-AN20, Rev -, 02-2018 Copyright (c) 2018 Cree, Inc.

Example Application: Double Pulse Measurements Cree's KIT8020-CRD-5FF0917P-2 evaluation board will allow the user to make double pulsed clamped inductive switching measurements. Figure 14 is showing an arrangement in which Cree's KIT8020-CRD-5FF0917P-2 evaluation board should be connected in order to make the switching measurements. Figure 14. Clamped Inductive Switching Measurement Circuit A precision current measuring device will be required in order to measure current through Q1. There is a connection point (J9) on the board that can used to view current on an oscilloscope. T&M Research Products Inc. makes a viewing resistor (P/N # SDN-414-01) (as shown in Figure 15) that has a resistance of 10 m (which typically works well with most of the oscilloscopes with probe attenuation set to x100), that is sold separately, and that may be used with Cree's KIT8020CRD-5FF0917P-2 evaluation board. If a different value of resistor is chosen, then the user should make sure that the resistor has minimal insertion inductance. If current does not need to be viewed, then the 1/4" shorting strip (which comes with Cree's KIT8020-CRD-5FF0917P-2 evaluation board) should be soldered into J9. Note: Either a current measuring device or the shorting strip must be soldered into place (J9) before operating this board. Figure 15.

The information in this document is subject to change without notice. Cree, the Cree logo, and Zero Recovery are registered trademarks of Cree, Inc. 18 Due to the fast switching speeds associated with Cree SiC MOSFETs, the following steps must be followed closely to yield the most accurate results possible. Scope probes measuring drain to source voltage (VDS) and gate to source voltage (VGS) must have minimal loop area between the signal and the ground. The oscilloscope probes measuring VDS and drain to source current (IDS) must be de-skewed. Bulk capacitance may need to be added to the board to minimize DC link voltage sag during twopulse measurements. The amount will vary based on desired current level and the pulse width. Figure 16 shows a two-pulse experimental setup. Figure 17 shows the measured waveforms. Green waveform shows the output current, pink waveform shows the gate signal and yellow waveform shows the output voltage. Figure 16. Two-pulse setup Figure 17.
