Triple Active Bridge converter design, analysis and results

In this project, an advanced architecture and control of multi-port converter (MPC) system where the sources and storage system are integrated through an actively controlled and galvanically isolated power electronic network that can allow and regulate the power flow in any desired direction. The AC output port of the PCS is configured as a standalone grid of adjustable voltage/frequency/power, which, in this project, is set as 120V AC RMS, 60Hz with a power rating of 2kW. The proposed network can integrate both solar and wind renewable energy sources to a controllable DC link, which acts the input port (port-1) for the proposed triple active bridge (TAB) converter. While the port-2 serves AC load demand, port-3 is tied to an energy storage system, which is capable of both sourcing and sinking power depending on its state-of-charge (SoC). The proposed power conversion architecture will be employed in PV-wind-ESS-grid coupled four-port system (port-1: solar PV – source; port-2: wind – source; port-3: energy storage – source/sink; port-4: AC grid - sink) that is envisioned as the backbone of power systems in remotely located disadvantaged communities.
