This paper presents a hybrid technology approach serving as an entry point in the industry of SiC devices at high power levels. The proposal consists of paralleling SiC Schottky diodes with high speed IGBTs in a baseplate-less and solder free module to alleviate the high cost of wide band gap devices, improve performance of the converter and also enhance its reliability. An experimental inverter rated...
Conventional solar power conversion systems utilize one stage architectures. This paper is devoted to the two stage approach, where a three level DC-DC converter is adopted to maximize the power transfer between the source and the load. Two 500kW DC-DC converters are developed as part of a 1MW utility scale system and principal results are provided to highlight achieved performance obtained from the...
