摘　　要：研究了一种单周控制高频链反激DC-AC变换器,该逆变器由高频变换器、周波变换器及高频储能变压器构成。通过有序地控制各开关管的通断,实现了正弦交流电的输出。对基于工作在电感电流连续模式的反激逆变器,在同步整流的基础上提出了单周控制策略,提高了逆变器的控制精度和响应速度,增强了抑制扰动的能力。最后详细介绍了电路的工作原理和控制原理,通过实验验证了理论的正确性,证明了电路的可行性。A novel one-cycle control high frequency link flyback DC-AC converter is presented,which inverter consist of high frequency converter,cycloconverter and high frequency energy storage transformer.By controlling each power FET in order,it could output a sinusoidal alternating current.One-cycle control strategy is established on flyback inverter which working under the inductor current continuous conduction mode,and based on synchronous rectification,which improves the control precision and response speed,and enhances the ability to suppress disturbances.The working principle and circuit control principle are described in detail.Experimental results show the correctness of the theory to prove the feasibility of the circuit.
