Abstract
The applications of direct current are limited in medium and high power systems because of the problems in switching. In this paper, a circuit of a multi-stage dc hybrid switch is proposed for medium-power (10kW) highly-inductive dc systems. Based on the multi-stage switching strategy, a slow switching method is further studied for limiting the overvoltage to power semiconductor devices. The feasibility of the circuit, the strategy, and the method for a 10 kW inductive DC system is verified by both simulation and prototype tests. The limitation and potential of the multi-stage hybrid switching concept for higher power- level systems are additionally discussed.
