This paper presents a topology of a multi-port phase shift converter for integration with a photovoltaic (PV) system, a wind turbine generator, and a battery to supply a grid-connected domestic load. The main advantage of the topology is using a multi-winding high-frequency transformer (MWHFT) to integrate the input and outputs of the system. In contrast with the case of using a common electrical bus, using MWHFT presents several advantages, such as isolating the converter ports, the easier matching of different voltage levels of the converter ports by adjusting turns ratio, simpler power flow control between the converter ports by applying leading or lagging phase shift angles, and eliminating the leakage current flow through the PV panels from the utility grid. A detailed analysis of the proposed topology and the control system is presented. A numerical simulation of the proposed system is carried out to confirm the system operation and control technique. The experimental tests have been conducted on a prototype converter to approve the proposed system performance.

In this paper, a topology of a multi-input renewable energy system, including a PV system, a wind turbine generator, and a battery for supplying a grid-connected load, is presented. The system utilizes a multi-winding transformer to integrate the renewable energies and transfer it to the load or battery. The PV, wind turbine, and battery are linked to the transformer through a full bridge dc-ac converter and their energy supplied to a grid-connected single-phase inverter and loads. A phase-shift control technique is employed to control the power flow between the sources and loads and the grid. To control the power flow, simple PI controllers have been used. The operation details and control techniques of the system are presented and also validated by using numerical simulations.
