Analysis of quasi Y source inverter with maximum boost control technique

Abstract

This paper presents the analysis of Maximum Boost control technique of Quasi Y source inverter. The technique uses shoot through states in inverter to achieve higher voltage boost. The control technique has been analyzed for voltage gain and its variation with modulation index, voltage stresses and nature of input current. A third harmonic injection method in maximum boost control has also been analyzed which further improves performance of inverter. A hardware prototype has been implemented to verify the simulated result.
