摘要：

A 30-kVA high-frequency link converter, which consists of 6×5 kVA center-tap power block topologies operating in parallel, is considered for battery-fed dc-ac converter applications. Practical solutions on minimizing circulating currents between the different power blocks, avoiding transformer saturation in forced commutated center-tap topologies and minimizing transistor on losses, are incorporated and illustrated by means of practical measurements and results. A simple single-capacitor snubber network, operating in parallel with a second-stage capacitor snubber, is used for these converter types. Typical applications include mobile and telecommunications uninterruptable power supply (UPS) systems, high ac-voltage loads fed from photovoltaic or hybrid energy systems, and battery-fed mobile variable-speed ac and dc drives. © 1990 IEEE
