Abstract
This research serves as basis to investigate the total energy losses in DC-DC
converter circuit. The circuit used for the investigation was the inductive load
chopper circuit .Two diodes were used one is the Silicon PiN diode (8A/600V) the
other is Silicon Carbide Schottky diode (6A/600V).The waveforms of current and
voltage diode under test ( DUT) and IGBT are measured respectively and
compared them with the simulation results. The gate resistance G R was also
changed to further investigate the effect of di/dt of the DUT current during turnon
of the switch on the total energy losses in the system.
