Synchronous power converter system

A synchronous power converter system, comprising:

• a processer circuit configured to output a plurality of clock signals having the same frequency;
• and
• a plurality of power converters configured to respectively receive the plurality of clock signals, wherein each of the power converters includes an oscillator circuit, a frequency detector circuit, a compensator circuit, a controller circuit and a switch circuit, the frequency detector circuit is connected to the processer circuit, the oscillator circuit and the compensator circuit, and the compensator circuit is connected to the controller circuit;
• wherein the oscillator circuit outputs an oscillation signal, the frequency detector circuit receives the clock signal and the oscillation signal and detects a clock frequency of the clock signal and an oscillation frequency of the oscillation signal to output a frequency detected signal, the compensator circuit outputs a compensating signal according to the frequency detected signal, and the controller circuit controls the switch circuit according to the compensating signal.
