The development of a Solid State Transformer (SST) that incorporates a DC-DC multiport converter to combine both Photo-Voltaic (PV) power generation and battery energy storage. The DC-DC stage is based on a Quad Active-Bridge (QAB) converter which not merely provides isolation for the load, but also for the PV and storage. The AC-DC stage is implemented with a Pulse-Width-Modulated (PWM) single phase rectifier. Terminology to determine the power rating of the MAB ports is also derived.
