Abstract：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.
