Abstract
A power conversion system, a non-transitory computer readable medium, and a method of operating a power conversion system, in which inverter switching control signals are generated in a first mode according to an inverter carrier signal having an inverter switching frequency, and according to inverter modulation signals, to operate switches of an inverter to provide an AC output signal, and the inverter modulation signals are shifted in a second mode for low modulation index values to reduce common mode voltage.
