This article 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 . . This article 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 . . Abstract:The traditional Fixed Band Hysteresis Current Control (FB-HCC) though being widely used for the current control of grid integrated voltage source inverter (GI-VSI), has the drawback of variable switching frequency. To overcome this drawback, Complex Programmable Logic Device (CPLD) based switching. . ock diagram of the single phase bridge power inverter (Fig. The proposed hysteresis current controller combines the advantages of both symmetrical unipolar PWM and hysteresis techniques.
