In the voltage source inverter, a suitable circuit designed to protect the inverter against a short-circuit fault is a critical problem, because such a fault will cause permanent damage of the system. Recently, a new bis loop overcurrent limiting circuit was proposed. In this paper, both computer simulation and circuit experiment are used to investigate its effectiveness and the influence of the reverse recovery characteristic of the diode on the protecting process. Both results show, with a carefully chosen GTO turn-off time, the new approach is preferred.
