Abstract

A multi-channel power system and a method of controlling a phase shift of the same are provided. The multi-channel power system includes one or more first DC to DC converters and one or more second DC to DC converters. The first DC-DC converter outputs a first pulse width modulated signal having a first default frequency. When the first DC-DC converter receives a reference clock signal, it outputs the first pulse width modulated signal having a frequency that is the same as that of the reference clock signal. The first DC-DC converter outputs a phase-shifted clock signal having a preset phase shift relative to the first pulse width modulated signal. The second DC-DC converter outputs a second pulse width modulated signal having a second default frequency. The second DC-DC converter outputs the second pulse width modulated signal having the preset phase shift according to the phase shift clock signal.
