摘　　要：提出并深入研究了双向大升压比直流变换器型逆变器电路拓扑、控制策略、稳态原理特性、电压传输比的推导方法和关键电路参数的设计准则,给出了仿真和原理实验结果。这种逆变器是由两个相同的、输出反相的低频正弦脉动直流电压的双向功率流大升压比的直流变换器以差动电路构成。理论分析、仿真和原理实验结果表明,这种逆变器具有电路拓扑简洁、双向功率传递、升压比大、功率密度高、输入电流纹波小、控制简单、负载短路时可靠性高、应用前景广泛等优点,为实现大升压比的大容量逆变器奠定了关键技术基础。The circuit topology, control strategy, characteristic of steady principle, derived method of voltage transmission ratio,and design criteria of key circuit parameters of the bi-directional Boost DC/DC converter mode inverter with high voltage transmission ratio are proposed and deeply investigated in the paper. The simulation analysis and the principle test results are given. This kind of inverter is differentially constituted of two same bi-directional Boost DC/DC converters with high voltage transmission ratio which produce out of phase low-frequency sinusoidal pulsate DC output voltage. The theoretical analysis, the simulation and the principle test results demonstrate that this kind of inverter which have the advantages of simple topologies, bi-directional power transmission, high voltage transmission ratio, high power density, small input current ripple, simple control, high reliability under short-circuit, wide application prospect and so on, and provide key technical fundamental for large capacity inverter with high voltage transmission ratio.
