摘　　要：本文提出了一种新颖的单级式升压逆变器,该逆变器是由两路反激电路分别工作于整个逆变器的正负半周期,在负载处并联叠加而构成,不仅保留了反激电路结构简单、输入输出电气隔离和升降压范围广等特点,而且克服了单端反激电路只能单向输出的缺陷,实现了双向输出实现逆变。同时本文对该逆变器的工作原理、控制策略和电路关键参数进行了分析。通过仿真和实验验证了理论的正确性和实际的可行性。A kind of novel single-stage inverter which is boosted is presented in this paper, and the inverter is constituted by two way flyback circuit working in the positive and negative half period of the inverter and adding parallel on the load. It not only retains the characteristics such as simple structure,isolating input/output and wide range booster of the flyback circuit, but overcomes the defect of single-ended flyback circuit which only has one-directional output, and realizes the bi-directional output and achieves inverter. At the same time, the operation principle, control strategy and key parameters of inverter circuit are analysised in this paper. The correctness of the theoretical and practical feasibility are verified by the simulative and experimental results.
