[0031] The drawings show specific embodiments of the present invention, and the present invention will be further described below through the drawings and embodiments.
[0032] As a preferred implementation of the power module test system, such as figure 1 The power module test system shown includes:
[0033] Oscilloscope 2, multimeter 3, current probe 4, inductor 5, pulse generator 6, drive module 7, high-voltage power supply 8, low-voltage power supply 10, pulse generator 6 to generate pulses with variable widths, which are amplified by drive module 7 to control power switching devices The on-off of the IGBT is used to control the output voltage and current of the IGBT power module 1 to achieve the purpose of evaluating the performance of the power device. The low-voltage power supply 10 provides 5V power to the pulse generator 6 and 5V, ±15V power to the drive module 7. The high-voltage power supply 8 is used to charge the capacitor 9 of the IGBT power module 1 under test. The...
