Modified High Boost quasi Z-Source Inverter with an Active Switched Network

In this paper, a novel High Boost quasi Z-Source Inverter with an Active Switched Network is introduced for higher boost applications. The proposed network configuration is designed to have higher boost factor than the conventional high boost active switched quasi Z-Source inverter by means of adding a capacitor in place of a diode in the impedance network. The proposed network topology also contributes common grounding and continuity of input current. The major advantage of the proposed network is its capability of providing higher boost with smaller duty ratio when compared to high boost quasi Z-Source inverter. And also the proposed network has lower stresses on the active components. This paper also includes the working, steady-state analysis, parameter selection of the proposed network topology. And also the performance of the proposed network is compared with the DC links of various other topologies that are capable of providing higher boost factors. At the end, the simulation results of the proposed network are compared with theoretical calculations and verified.
