Voltage conversion system and control method thereof

Abstract

The present disclosure provides a voltage conversion system and control method thereof. The voltage conversion system includes a multiphase voltage convertor and a controller. The multiphase voltage convertor is coupled to a load, and includes multiple phase circuits, in which the phase circuits are coupled to the load, and at least one of the phase circuits is in an active state, so that the multiphase voltage convertor provides load current to the load. The controller is coupled to the multiphase voltage convertor, is used to enable at least one of the phase circuits to be in the active state according to the load current and an activation sequence of the phase circuits, and is used to adjust the activation sequence to adjust a first one of the phase circuits from a second activation item to a top priority activation item in response to that an enable amount of the phase circuits becomes
