Abstract
This application provides a power supply system and a conversion method. The power supply system includes a power generation apparatus, a converter circuit, and a drive control circuit. The drive control circuit may be configured to: when a power grid fails, control, based on duration of previous low voltage ride-through, the converter circuit to increase a value of a current to be output to the power grid from a first operating current value to a low voltage ride-through current value, to increase a voltage value at an output end of the converter circuit. Herein, the previous low voltage ride-through is latest low voltage ride-through. In this application, the system can control, based on duration of previous voltage ride-through, a current to be output by the converter circuit to the power grid, to reduce circuit oscillation, with a simple structure, a simple control method, and high safety.
