Abstract
A multi-phase DC/DC power converter is provided with expandable circuits and comprises a main module and an expanded module. The main module has an n-phase PWM control circuit and n output circuits controlled by n-phase PWM control circuit to transform an input power to an output power. The expanded module comprises n expanded circuits parallel to the n output circuits respectively. Moreover, then expanded circuits share input current of the input power with the parallel n exported circuits via the n-phase PWM control circuit.
