    Abstract
  • Switched-inductor quasi-Z-source inverter and its improved version in terms of boost ratio cannot meet the stringent demands of new energy field, limiting the utilization of Z-source inverter in photovoltaic inverter and micro-grid. This paper proposes an enhanced switched-inductor quasi-Z-source inverter topology with a high voltage gain by changing the traditional switched-inductor quasi-Z-source inverter. On the basis of one switched-inductor cell, a new switched-inductor cell is added in the new topology, which avoids that the hardware structure is too complex and shoot-through duty ratio range is too narrow, and allows the boost ratio to increase 5-40 times; the continuous input current can be ensured. Moreover, both the capacitor voltage stress and inductor current ripple are effectively reduced in LC network X-shape structure. In this paper, the enhanced topology is theoretically analyzed in detail. On this basis, some simulations and experiments are carried out to validate the feasibility and superiority of the proposed topology.
