Control method for single-phase bidirectional inverter and device thereof

A control method of a single-phase bidirectional inverter is for the single-phase bidirectional inverter, and the single-phase bidirectional inverter includes a switch and an inductor. The single-phase bidirectional inverter control method includes an extraction step, a calculation step, and an integration step. The extraction step inputs a current command to the switch and obtains a current through the inductor. The current was piecewise linearized to extract a magnetizing inductance and a demagnetizing inductance of the inductor. The calculation step uses a duty ratio of the switch to calculate the change amount of the current of the magnetizing inductance and the change amount of the current of the demagnetizing inductance. The integration step integrates the change amount of the current of the magnetizing inductor and the change amount of the current of the demagnetizing inductor to obtain another duty ratio of the switch in the next cycle. Therefore, it is favorable for improving the ability of current t
