More on: Pre-Switch’s soft-switching power inverter

Earlier this week, Californian company Pre-Switch claimed 99.3% efficiency for a 100kHz electric vehicle traction inverter running at 100kW. It credits this impressive figure to the use of a resonant topology called ‘auxiliary resonant commutated pole’ (ARCP, one phase of three in diagram right) which enforces soft-switching – switching at either zero voltage or zero ...
