摘要：
Traditional DC-DC high-frequency isolated grid-connected inverter has the problems of high loss, voltage spike and low stability. A novel topology combining with parallel resonance and DC-DC converter was proposed. This novel topology can achieve zero voltage switching (ZVS) for the high-frequency switch, which reduces the loss of the inverter. The working principle and switch states are introduced in detail, then the resonant equivalent circuit model is built and its design principle of resonant parameters is given. To eliminate low harmonics generated by the dead-zone, the dead-time compensation is applied in the control system. Finally, a prototype is produced, and the experiments verify the correctness of the circuit topology and control strategy. © 2018, Electrical Technology Press Co. Ltd. All right reserved.
