Abstract

This paper describes a static reactive-power compensator using a soft-switching scheme. The proposed system is composed of a three-phase current-source inverter with an H-type soft-switching module, which consists of two semiconductor switches, two diodes, and an L-C resonant circuit. The operation of the proposed system was analyzed in detail through a theoretical approach and computer simulation with SPICE. A scaled prototype was built and tested for verifying the feasibility of hardware implementation. The proposed system would be suitable for a high-power application with less switching loss
