This paper introduces a single-phase current-fed inverter topology that enhance output voltage gain, eliminates leakage current, and reduces the number of active switches compared to conventional topology. Leakage current arises from high-frequency common-mode voltage in earlier single-stage boost inverters lacking electrical isolation. Moreover, traditional inverters face challenges in achieving grid amplitude AC output voltage due to their inherent step-down nature. To address these challenges, this study proposes an inverter configuration utilizing four active switches, two diodes, one capacitor, and an impedance source network Type-II, which incorporates three diodes and two inductors to enhance voltage gain. The configuration is connected in a common-ground arrangement between the output load and the input power source, thereby eliminating leakage current. In order to minimize the DC offset, the buffer network employs a single capacitor and makes sure the inverter operates symmetrically for both half-cycles of the AC output. Additionally, this proposed topology is well-suited for PV applications since it uses an appropriate PWM algorithm to regulate the operation of one of the four active switches in both shoot-through and normal modes. This study will provide clarity on the steady-state operating principle analysis. The study's contribution will also be evaluated, and its results will be examined.
