Abstract
A voltage conversion circuit and method, and a multiphase parallel power system, where in the voltage conversion circuit, a feedback circuit provides a frequency-controllable feedback ripple signal. Therefore, the voltage conversion circuit has a controllable operating frequency, and a frequency requirement of a load may be met. Compensation does not need to be performed in a hysteresis mode, and therefore the hysteresis mode has a fast-speed response. The operating frequency is fixed. Therefore, the voltage conversion circuit in the embodiments may be applied to the multiphase parallel power system such that the multiphase parallel power system is applicable to an application scenario with a large load current.
