Objectives: The variable output voltage from the wind energy conversion system is effectively regulated through the Solid-State Transformer (SST) using Dual Active Bridge (DAB) converter employing a Triple phase shift (TPS) control technique. Methods: A wind energy based system integrated with SST employing a DAB converter is proposed. The system comprises of Permanent Magnet Synchronous Generator (PMSG) based Wind Energy System (WES), SST, and resistive load. The SST provides an easy interface between the load and the WES.MATLAB Simulink-based analysis is done to compare the various control techniques used for DAB dc-dc converter. Findings: The DAB converter provides several benefits including its ability to provide bi-directional power flow, making it suitable for use in applications where power can flow in either direction, such as renewable energy systems. The Single-Phase Shift (SPS) is among the majorly adopted control strategies for DAB converters however it performs unsatisfactorily with varying load conditions. In this paper, a Triple- Phase Shift (TPS) control strategy has been reported. A detailed mathematical analysis along with MATLAB Simulink based results suggest that this control technique reduces current stress on semiconductor switches by reducing peak inductor current by almost 23% and 9% as compared to conventional phase shift modulation technique, therefore, improving the efficiency of the converter. Novelty: The phase shift ratio used in the TPS control technique for the DAB converter is modified by incorporating a virtual power component that enhances the dynamic response of the output voltage.
