Active Power Decoupling Topology for Single Phase Bridge Inverter based on Buck-Boost Convertor

Abstract

Increasing demand of power has led to exploration of non-conventional sources of energy. Solar energy has been the most exploited source of energy in this regard. Effectiveness of power utilization depends on the power conversion from AC to DC. Further improvement in utilization of DC power depends on the DC-DC conversion steps involved. The planned methodology offers a study of power decoupling method while no further power semiconductor are used for a DC to 1-ɸ AC device. 1-ɸ voltage source bridge inverters have primarily two drawbacks, that's reduction in DC voltage usage and disparity in power among the incoming and outgoing sides. These difficulties have been looked upon and a topology has been implemented that uses just a film capacitance beforehand buck-boost convertor that is linked to the voltage-source bridge inverter. Reenactment and preliminary outcome confirmed the credibility of the planned power decoupling technique on the 2-stage 1-ɸ bridge inverter by buck-boost convertor.
