Abstract
A controller for controlling a multi-phase power conversion system includes a pulse width modulation (PWM) comparator configured to generate a PWM signal based on a ramp signal, a voltage reference signal and a feedback voltage from the power conversion system. A circuit may be configured to generate, based on the PWM signal, PWM signals by delaying the PWM signal with different delay times, and feed the PWM signals to respective switching power converters of the multi-phase power conversion system, to regulate an output voltage of the power conversion system. Each switching power converter may include a control circuit configured to adjust a pulse width of a received PWM signal based on a reference current and an output current of a corresponding switching power converter, to generate an adjusted PWM signal, based on which, an output voltage of the corresponding switching power converter is regulated.
