针对单相电压源型逆变电源并联工作的需求，提出了一种电流内环采用比例控制、电压外环采用比例谐振控制的新型控制方案。在获得逆变电源控制框图的基础上，推导了该控制方案下单相逆变电源的传递函数，并基于传递函数给出了控制器参数的设计过程。对等容量情况下和不等容量情况下的不同负载性质的逆变电源并联系统进行了仿真研究，结果表明该控制方案具有良好的适用性，具有一定的应用价值。

According to the need for single-phase voltage inverter parallel operation , a new control scheme is introduced .In the scheme a proportional controller is used in current-inner-loop and a propor-tional resonant controller is adopted in voltage-outer-loop.By achieving control block diagram of the con-trol system , the transfer function of single-phase voltage inverter power is deduced and the design process of the control parameters is demonstrated based on the transfer function .Then this paper explores inverter power parallel system of different loads with equal and unequal capacities .Its simulation results show that the suggested controller is of favorable applicability and significance .
