Combined boost inverter system based on switch inductance-capacitance network and control method thereof

The invention relates to a combined boost inverter system based on a switch inductance-capacitance network and a control method of the combined boost inverter system. The combined boost inverter system comprises an input direct current source, the switch inductance-capacitance network, a single-phase high-frequency combined modulation switch, an LC filter and a load. The input direct current source, the switch inductance-capacitance network, the single-phase high-frequency combined modulation switch, the LC filter and the load are cascaded in sequence. Compared with a traditional Boost type boost inverter system, the boost inverter system has the advantages that input and output current ripples are small, the input and output voltage transmission ratio is doubled, the size is small, the weight is light and the like, and the boost inverter system is suitable for small and medium-capacity inversion occasions. 本发明涉及一种基于开关感容网络的组合式升压逆变系统及其控制方法,包括输入直流源、开关感容网络、单相高频组合调制开关、LC滤波器和负载；所述输入直流源、开关感容网络、单相高频组合调制开关、LC滤波器和负载依序
