초록

This paper proposes a new reactive-power compensator composed of a soft-switching current-source inverter. The compensator consists of 3-Phase IGBT bridge, dc reactor, and a resonant circuit. The resonant circuit offers the IGBT bridge to have PWM operation with minimal switching losses. A theoretical analysis and computer simulation with Is-Spice were done to verify the operation of the proposed system. Also a acaled-model of the system was built and tested for verifying the feasibility of proposed system.
