: In this work, a control strategy for power flow management of a grid-connected hybrid photovoltaic (PV)– wind-based system and battery with an efficient multi-input transformer coupled bidirectional DC–AC converter is presented. The system aims to satisfy the load demand, manage the power flow from different sources, inject the surplus power into the grid when required. A transformer-coupled boost half-bridge converter is used to harness power from wind, while a bidirectional buck-boost converter is used to harness power from PV. This system is mainly focused on improving the dc-link voltage regulation. The series or parallel configuration can be extended at the output to derive multiport DC–AC converters. A multi-input dc/dc converter based on the flux additively is proposed in this paper. Instead of combining input dc sources in the electric form, the proposed converter combines input dc sources in magnetic form by adding up the produced magnetic flux together in the magnetic core of the coupled transformer. With the phase-shifted pulse-width-modulation (PWM) control, the proposed converter can draw power from two different dc sources and deliver it to the load individually and simultaneously. The operation principle of the proposed converter has been analysed in detail. The output voltage regulation and power flow control can be achieved by the phase-shifted PWM control. A prototype converter with two different dc voltage sources has been successfully implemented. Computer simulations and hardware experimental results are presented to verify the performance of the proposed multi-input dc-ac converter.
