摘要
Abstract
A new quasi-Z-source inverter called switched-inductor quasi-Z-source inverter was presented which employs a switched-inductor impedance network to couple power source and the invert main circuit.Compared with the traditional quasi-Z-source inverter, the switched-inductor quasi-Z-source inverter increases the voltage conversion rations, has an obvious voltage boost ability, and for a given voltage conversion ration, a higher modulation index can be used to ensure a good output power quality.Theoretical analysis, the experimental and simulative results based on the simple boost control strategy and the third harmonic injection control strategy verify the superiority and rationality of the new quasi-Z-source inverter and demonstrate the features of the third harmonic injection control strategy.关键词
