Abstract
The present disclosure discloses a control circuit and a control method for a multiphase power supply and the multiphase power supply. The control circuit includes a current reference signal generator and a controller. The current reference signal generator is configured to adjust a first compensation signal according to a first scaling factor and a first voltage signal, so that the first compensation signal follows the first voltage signal in a steady state, and a current reference signal is obtained according to the first compensation signal and the first voltage signal. The controller is configured to obtain a control signal for each phase power conversion circuit according to the current reference signal to control each phase power conversion circuit to provide a power output to a load. The present disclosure can improve a phase-conversion stability of the multiphase power supply, and can achieve fast and accurate control of the multiphase power supply.
