Abstract
This paper presents a single stage, unidirectional, three level, three phase high frequency link inverter topology. The proposed topology can be used for applications like grid integration of renewable energy sources such as fuel cell, solar photovoltaic where power flow is mainly unidirectional. The use of high frequency transformer reduces overall system volume and cost as well as improves power density. The switches in primary side of the proposed converter are soft-switched. As the primary side converter has multilevel structure, voltage stress on the switches are also reduced. The secondary side switches are switched only at line frequency leading to negligible switching loss. An analysis of operation of the proposed converter is discussed in details. Key simulation results are presented demonstrating the effectiveness of the proposed topology.
