A switched-boost topology for renewable power application

This paper proposes a novel switched-boost converter suitable for microgrid application. The proposed converter can provide a DC output, which is greater than the input voltage. Apart from a DC, it can be, simultaneously, used to supply an AC load. In order to supply an AC load it has to be cascaded with a Voltage source inverter (VSI). While operating with a VSI, it avails all the advantages of a Z-source inverter, with half the number of passive components. During AC operation, it prevents the shoot-though current due to mis-gating and provides superior noise immunity. The circuit operation, analysis, PWM control strategy, and experimental results are provided to verify the proposed topology.
