Abstract A novel single phase voltage mode quasi-Z-source inverter circuit topology and control strategy were proposed. The circuit topology, single polarity SPWM control strategy with energy storage capacitor voltage feed forward control of impedance network and feedback control of output voltage, characteristic of steady principle of this inverter were deeply investigated, and the important conclusions and the design criteria of key circuit parameters of this inverter were obtained in the paper. This kind of inverter is cascade composed of impedance network with high voltage transmission ratio, single phase inverting bridge and single phase filter. The impedance network with high voltage transmission ratio is composed of energy storage inductance L0 and two DLCC type with two ports impedance network units connected in cascade. The theoretical analysis and the experimental results have demonstrated that this kind of inverter has the advantages of simple topologies, high voltage transmission ratio, high power density, low output voltage distortion, high reliability, flexible input voltage, low cost, wide application prospect and so on.
