In this paper, performance of a high gain quasi Y-source impedance network converter is analysed. This converter has a high voltage gain while using a small duty ratio. Compared to other impedance source converters, Y-source converter operates with lower shoot-through duty cycle for the same boosting gain. To achieve that, a three windings transformer with very low leakage inductance is employed. In turn, the switching losses and heating are low at the same boosting gain. Moreover, in this type of converter, the boosting gain depends on number of variables, and hence more degrees of freedom for meeting design constraints. The voltage and current of the switching elements are analysed during shoot and non-shoot through. The analysis shows that for high boosting gain some components have high voltage stress compared to conventional converters. Moreover, fast switching diodes are required to achieve high boosting gain. The performance of the proposed converter is analysed using numerical simulation and experimental testing.
