Abstract

Power circuits used in prototype applications for flexible AC transmission systems (FACTS) have consisted of multiple three level or neutral point clamped power converters interfaced to the power system using transformer arrangements for improving waveform quality. This paper presents analytical modeling to determine semiconductor losses in such multi-pulse voltage source DC-AC converters used for FACTS applications. Device current and voltage waveforms during all operating conditions are used to develop behavioral loss models to determine power losses in each of the power semiconductors constituting an inverter pole. The results are used to determine the total power losses in an SSSC application. Computer simulation waveforms are used to demonstrate overall system performance.
