Abstract

A soft-switching three-level chopper-inverter system was built for high-power applications like Power Conditioning System (PCS) for Superconductive Magnetic Energy Storage (SMES). The system can handle 1800-VDC, 200-A peak, and 250-kW output power. The system was designed to operate with 20-KHz PWM operation with the aid of state-of-the-art zero-current transition type soft-switching. The system is based on the Power Electronics Building Block (PEBB) concept.
