ABSTRACT:
The present invention relates to a power converter, using input voltage provided by a fuel battery and processing an electrical characteristics transformation on the input voltage to output an output voltage to loading. The power converter comprises: a multiple-phase PWM controller to output multiple PWM control signals in accordance with the voltage level of output voltage; a multiple phase bridge converter to input and output the input voltage in accordance with the multiple PWM control signals; and a transformer to input and process an electrical characteristics transformation on the input voltage from the multiple phase bridge converters to output the output voltage. The multiple-phase PWM controller further comprises a PWM generator and at least one phase shifter.
