Abstract

Output dc voltage from Fuel Cell (FC)/Photo Voltaics (PV) needs to be conditioned and converted into ac form before integrating to grid. Normally, two stage converters are used for this purpose. Two stage converters have several disadvantages like low efficiency, more number of components, big size, etc. especially when they are operated at low input voltages. In this paper, a coupled inductor based high performance, high gain, single-stage inverter topology, which can be used for grid connected FC/PV applications or stand-Alone applications is proposed. In the proposed topology, dc-dc power conversion and dc-Ac power conversion can be done in a single stage. The proposed topology has several features such as high gain, low cost and compact size. This topology suits well for low power applications. The principle of operation, steady state analysis of the proposed topology is presented in this paper. The steady state analysis is verified by a simulation, simulation results of the proposed converter for an ac load is presented.
