一种用于SiC-MOSFET串联的新型有源电压钳位电路拓扑

Series-connection of silicon carbide (SiC)-MOSFETs is an attractive method to achieve a high-voltage and fast-switching power semiconductor switch. In order to deal with the unequal voltage sharing problem in such series connection method, a novel active voltage clamping circuit topology is proposed in this letter. The maximum drain-source voltages of the series-connected SiC-MOSFETs are clamped b...
