High Frequency Power Supply with 3.3 kV SiC-MOSFETs for Accelerator Application

摘要

Pulse switching characteristics of newly developed 3.3 kV SiC-MOSFET were investigated and they were provided for a prototype switching power supply (SPS). With supply voltage of 2.5 kV and the load resistor of 100 Ω, rise time T_r and fall time T_f were 76 ns and 88 ns respectively. The SPS exhibited a successful 2.5 kV-20 A-1 MHz burst mode operation.
