Single-stage high-frequency isolation multi-input grid-connected inverter control method and related equipment

According to the single-stage high-frequency isolation multi-input grid-connected inverter control method and related equipment disclosed by the invention, each path of input source generates an MPPT error amplification signal through a maximum power point tracking MPPT loop control module; wherein the MPPT loop control module comprises a difference value between an output voltage and an output current of an input source and a voltage and current reference value corresponding to a maximum power point, and a PI regulator; generating a reference signal and a feedback signal of a grid-connected current according to the MPPT error amplification signal and a power grid voltage synchronization signal; and calculating a driving signal and a matrix converter switching signal by using a preset control model based on the reference signal and the feedback signal of the grid-connected current, and supplying power to each energy input end in a time-sharing manner. According to the invention, the waveform quality of the gr
