Testing Methodology for Wide Bandgap High Power Converter with Limited Lab Resources

Wide bandgap (WBG) power semiconductors devices are being adopted in high-power electronics applications at an accelerated rate. However, how to power up and test the converter properly with limited lab resources has rarely been discussed. This paper discusses the testing methodology of a high-power converter with limited lab resources and minimum energy consumption. Such a methodology enables the evaluation of the switching characteristics, thermal management performance, and full power rating continuous operation. The testing of a 75kW converter is given as an example.
