Abstract

A power conversion system includes at least two power converters and a current sharing bus, each power converter including a switching circuit, a power conversion circuit configured to receive an input voltage via the switching circuit and to provide a local output current, an output sense circuit configured to detect the local output current and to generate a local output current sense signal, a current sharing terminal coupled to the local output current sense signal via a resistor and coupled to the current sharing bus; and a PWM controller configured to adjust a duty cycle of the switching circuit based at least in part on the local output current sense signal provided by the output sense circuit and an average current signal on the current sharing bus.
