This paper presents a novel coupled inductor based high boost inverter topology which can be utilized in low voltage renewable systems where high voltage step-up is needed to interface with 110 Vt220 V AC systems. The proposed inverter possesses high boost ability with superior EMI immunity compared to a traditional voltage source inverter (VSI). Unlike the traditional VSI, the proposed inverter does not need dead time circuit for its switching signals as it utilizes shoot-through state of the inverter in its single-stage configuration. Insertion of shoot-through state also helps it to achieve high boost operation essential for renewable energy applications. The proposed inverter is derived from Current-Fed Switched Inverter topology. Apart from topology derivation, this paper describes the steady state analysis of the inverter and establishes the relation between input, DC-link, and AC output. An experimental prototype is built to validate the proposed inverter circuit. A 220 V (rms) AC is obtained from 52 V DC input to demonstrate its boost mode of operation.
