Abstract: A power converter includes N power conversion units. Each power conversion unit includes a main switching circuit, a transformer, a synchronous rectifier circuit, an input signal terminal and a signal processor. A primary winding of the transformer is connected with the main switching circuit. The synchronous rectifier circuit is connected with a secondary winding of the transformer. The input signal terminal receives a first PWM control signal. The signal processor generates first and second PWM driving signals to drive the main switching circuit according to the first PWM control signal, and a phase difference between the first and second PWM driving signals is (180±θ) degree. The signal processor generates third and fourth PWM driving signals to drive the synchronous rectifier circuit according to the first PWM control signal, and a phase difference between the third and fourth PWM driving signals is (180±θ) degree.
