<div> This paper proposes that the control process of the single-phase full bridge inverter circuit is equivalent to two buck circuits, and the control strategy of the DC-DC circuit is adopted to enable the output voltage to track the given sine wave target value in real time, realizing the control of the inverter circuit, simplifying the control process, and enhancing the anti-interference ability of the system. On the basis of traditional discrete sliding mode control, a new adaptive approach rate is introduced,…
