Abstract :
A new bridge-type chopper topology using MOSFETs is proposed and studied for superconducting magnetic energy storage (SMES) applications for use in low-voltage end-user sides. Both the bridge-type and conventional choppers are theoretically analyzed and experimentally compared. The dynamic energy exchange characteristics of SMES for solving the voltage swell and voltage sag problems are presented. The results obtained demonstrate that the bridge-type chopper has higher energy utilization efficiency than the conventional one.
