In order to test the switching characterization of IGBT in value state,an off-line insulated gate bipolar transistor(IGBT)switching characteristics measurement system was designed.The control of test platform is based on computer,the bus voltage is provided by the charging capacitor,the double pulse used to test is controlled by DSP,and the high-performance oscilloscope is adopted for the data acquisition and storage,computer is used for post-data processing.With the waveforms of voltage and current during ...
