Grid-Forming Microinverter and Method Based on Bidirectional Flyback Converters

Disclosed in the present disclosure is a grid-forming microinverter and method based on bidirectional flyback converters, relating to the technical field of photovoltaic power generation. The method includes: calculating active power and reactive power through an output voltage and an output current of the grid-forming microinverter; generating a reference signal of a voltage loop by using a preset power reference value based on a power loop control principle; generating a reference signal of a peak current control loop according to an actual output voltage; and generating, according to primary-side current signals of the first bidirectional flyback converter and the second bidirectional flyback converter, a drive signal for each switch tube under regulation of the peak current control loop.
