Abstract
Systems for operating a rectifier are provided. Aspects include a rectifier including a set of bridge structures configured to receive an input current of a power supply, wherein each bridge structure in the set of bridge structures includes a set of diodes and a set of active switches, wherein each active switch in the set of active switches is configured to provide a parallel path around each diode in the set of diodes when in a PWM state, a controller configure to determine a threshold current for the rectifier and operate one or more active switches in the rectifier in a PWM state based on the input current being less than the threshold current.
