Comparison of three phase current source inverters and voltage source inverters linked with DC to DC boost converters for fuel cell generation systems

Abstract

Three phase current source inverters (CSI) and voltage source inverters linked with a DC to DC boost converter (VSI+BC) are appropriate solutions to convert electrical energy for distributed fuel cell generation systems. The performance of CSI's and VSI+BC's in this application is shown and both topologies are compared to each other concerning their power semiconductor design rating and their semiconductor power losses.
