氮化镓场效应管功率变换器开关损耗的时频域表征

This article presents a methodology for the time-frequency characterization of switching losses in Gallium nitride field effect transistors used in power electronics applications, particularly in dc–dc converters. Typically, switching losses are measured in the time-domain through the integration of the instantaneous power, that is, the product of the voltage multiplied by the current, during the ...
