The auxiliary commutated pole inverter (ACPI) is a PWM soft-switching topology usually employed for switching loss reduction. This work however investigates how the two traditional ACPI control schemes, fixed- and variable-timing, can shape the transitioning edges of the inverter's output voltage. Its frequency response can then be predicted and its high-frequency content mitigated, with potential enhancements to the inverter's Common Mode Electromagnetic Interference (CM EMI) performance. By addressing the EMI problem at source, lighter passive filters might be used, beneficial to applications where high power densities are desirable. A 5-kW, 3-phase ACPI prototype is utilized for proof of concept.
