5.1 Test Equipment

AC Voltage Source: The AC input source shall be capable of supplying between 85 VAC and 265 VAC at

no less than 8 A peak. Connect the AC source to the L and N terminals of J1 on the EVM as shown in

Figure 2. For accurate efficiency calculations, a power meter should be inserted between the neutral line

of the AC source and the neutral terminal of the EVM. For highest accuracy, connect the voltage terminals

of the power meter directly across the line and neutral terminals of the EVM.

12-V Bias Supply: The bias supply to the device shall be capable of supplying up to 12 VDC at no less

than 10 mA. Connect the bias supply to the – and + terminals of J2, UCC28180 12-V VCC bias, as shown

in Figure 2.

Output Load: A programmable electronic load set to constant current mode and capable of sinking 0 to 1

A at 390 VDC shall be used. Connect the load to J3, as shown in Figure 2.

Power Meter: For highest accuracy, power analyzer shall be used to measure the input power, THD, and

power factor. An example of such an analyzer is the Voltech PM100 Single Phase Power Analyzer.

Multimeters: For highest accuracy, the output voltage of the UCC28180EVM-573 shall be monitored by

connecting a digital voltmeter, V1, directly across TP11 and TP12 with the positive terminal at TP11 and

the negative terminal at TP12. A DC current meter, A1, should be placed in series with the electronic load

for accurate output current measurements.

Oscilloscope: A digital or analog oscilloscope with 500-MHz scope probes is recommended.

Fan: A fan, capable of 200 LFM to 400 LFM, should be used to maintain component temperatures within

safe operating ranges at all times during operation of the UCC28180EVM-573. Position the fan so as to

blow along the length of the heatsink as shown in Figure 2.

Recommended Wire Gauge: The recommended wire size is AWG #16 with the total length of wire less

than 8 feet (4 feet input, 4 feet return). The connection between the EVM output terminals (J3) and the

electronic load can carry as much as 1 A. The minimum recommended wire size is AWG #20, with the

total length of wire less than 8 feet (4 feet output, 4 feet return).

Test Setup

5.3 Power-Up/Power-Down Procedure

The following test procedure is recommended primarily for power up and shutting down the evaluation

module. Never leave a powered EVM unattended for any length of time. Also, the unit should never be

handled while power is applied to it or the output voltage is greater than 50 VDC.

WARNING

There are very high voltages present on the EVM. Some

components reach temperatures above 50°C. Precautions must be

taken when handling the board. Never operate the UCC28180EVM-

573 without the fan running. Always make certain the bulk

capacitors have completely discharged prior to handling the EVM.

1. Working at an ESD workstation, make sure that the ionizer is on before the EVM is removed from the

protective packaging and power is applied. Electrostatic smock and safety glasses should also be

worn. Because voltages in excess of 400 V may be present on the EVM, do not connect the ground

strap from the smock to the bench. If testing with a load, set the electronic load to constant resistance

mode.

2. Power-Up

(a) Connect the equipment as shown in Figure 2.

(b) Turn on the fan.

(d) Turn on the 12-V bias supply and verify that the output of the module is within regulation.

(e) Increase the load from 0 A up to 0.923 A.

5.4 Line/Load Regulation and Efficiency Measurement Procedure

1. For load regulation, use the test set up shown in Figure 2.

(a) Set the AC source to a constant voltage between 85 VAC and 265 VAC.

(b) Vary the load so that the output current varies from 0 A up to 0.923 A, as measured on DMM A1.

2. For line regulation, use the test set up shown in Figure 2.

(a) Set the load to sink the full-load current, 0.923 A.

(b) Vary the AC source from 85 VAC to 265 VAC

5.5 Output Voltage Ripple

1. Expose the ground barrel of the scope probe and place the tip of the probe on TP11, +VOUT, and rest

the exposed ground barrel of the probe on TP12, -VOUT, for output voltage ripple measurements.

5.6 Equipment Shutdown

1. To quickly discharge the output capacitors, make sure there is a load greater than 0 A on the EVM.

2. Turn off the AC source.

3. Turn off the Bias source.

6.3 Total Harmonic Distortion

Figure 5 shows the measured total harmonic distortion (THD). This design allows the converter to enter

into discontinuous current mode (DCM) at the higher line voltages which impacts THD. The converter still

meets the design goal of less than 10% THD at full load over the entire input line range despite using a

relatively small inductor that allows 40% inductor ripple current.

Figure 5. UCC28180EVM-573 Total harmonic Distortion

(as a function of line voltage and load current)

Figure 6demonstrates improved THD by doubling inductance (20% ripple).

Using swinging inductors which exhibit higher inductance value at lower magnetization (lowest current)

can also help to achieve low THD.Figure 7 shows the total harmonic distortion resulting from using a

current of 6.4 A (switching frequency = 18 kHz). The total harmonic distortion measures less than 5% from

50% load to full load under these conditions.

with L = 3.4 mH and fSW = 18 kHz

Figure 8 shows the total harmonic distortion resulting from a swinging choke that measured 530 µH at a

current of 6.4 A (switching frequency = 66 kHz). The total harmonic distortion measures less than 5% from

50% load to full load under these conditions.
