Abstract

This paper presents a control method for a single-phase differential Buck inverter without virtual quadrature based on dq coordinate transformation is proposed. This method converts the output of the two-phase bridge arm of the single-phase differential buck circuit to the dq frame for control, and can omit the one-phase virtual quadrature quantity additionally constructed in the traditional dq frame. For the two-phase capacitance imbalance problem in the control system, the symmetrical component method is used and then the corresponding phase sequence is transformed and controlled. Finally, the simulation proves that the proposed method can effectively realize the zero steady-state error control of the output voltage.
