Abstract
Provided are a soft-start method, a power converter system, and a household energy storage system, which are applied to the field of household energy storage technology and are used to improve the soft-start effect of a full-bridge resonant converter. The method includes the following manners: A soft-start process is configured as multiple operating periods, and a duty cycle is adjusted in periods and gradually increases; and in the soft-start process, according to the conversion of the duty cycle, a voltage is slowly output, and the value of the output voltage is gradually increased, so that the operating current in the soft-start process can be effectively controlled, thereby reducing the voltage stress of a power switch transistor when the power switch transistor is hard turned off.
