Feasibility study of 200 kW half-bridge and full-bridge DC/DC converters with 6.5 kV IGBTs

Abstract

This paper discusses the half- and full-bridge DC/DC converter topologies for high-power (200 kW) high-voltage (3.6 kV) applications. Focus is on the primary part of these topologies, i.e. the feasibility of two high-voltage IGBTs replacement in the full-bridge by two high-voltage film capacitors in the half-bridge.
