A power conversion system having spread spectrum and phase shifting mechanisms is provided. Each of a plurality of power converters of the power conversion system includes a spread spectrum instructing circuit, a synchronization signal detecting circuit, an oscillator circuit and a phase shifting circuit. The oscillator circuit outputs an oscillation signal according to a spread spectrum instruction parameter from the spread spectrum instructing circuit or a synchronization detected signal from the synchronization signal detecting circuit. The phase shifting circuit shifts phases of a plurality of waveforms of the oscillation signal to generate a clock signal. The phase shifting circuit of each of the plurality of power converters outputs the clock signal to a next one of the plurality of power converters. The synchronization signal detecting circuit of each of the power converters detects the clock signal to output the synchronization detected signal.
