Abstract
Control systems, methods and power conversion systems are presented for controlling common mode currents in power converters, in which feedback signals used in pulse width modulated inverter switching control are selectively adjusted to ensure minimum differences between the resulting common mode compensated feedback signals according to a common mode dwell time in each pulse width modulation period, with the common mode dwell time being adjusted according to modulation index.
