Abstract
A multi-switch types hybrid power electronics build block (MST HPEBB) least replaceable unit converter employs a first low voltage side (for example, 1000 volt power switches) and a second high voltage side (for example, 3000 volt power switches). The MST HPEBB LRU employs multiple bridge converters connected in series and/or in parallel, and coupled in part by a 1:1 transformer. To reduce weight and volume requirements compared to known PEBB LRUs, different power switch types are employed in different bridge converters. For example, in one exemplary embodiment, low voltage 1.7 kVolt SiC MOSFETS may be employed on the lower voltage side, while at least some 4.5 kVolt Silicon IGBTs may be employed on the high voltage side.
