This paper presents an experimental efficiency comparison study between two different direct AC-AC converter topologies: a direct matrix converter (DMC) and an indirect matrix converter (IMC). The evaluation is performed under variable load conditions using both discrete Silicon (Si) IGBTs and Silicon Carbide (SiC) MOSFETs working at power levels up to 9 kW. Each loss measurement is carried out using two power analyzers: one placed at the input and one at the output of the converter under study. To facilitate this measurement an output filter was necessary in addition to the normal input filter. Both converters are modulated the same traditional symmetrical space vector approach and feature an identical input/output filter design.
