Abstract

This paper presents the design of high-frequency transformer isolation bidirectional DC/DC converter based on solid-state transformer (SST). A phase-shift dual-active-bridge (DAB) converter is employed to achieve high-frequency galvanic isolation, bidirectional power flow, and zero voltage switching of all switching devices, which leads to low switching losses with high frequency operation. Moreover, a master-slave control (MSC) strategy is designed for the DAB stage of SST system to reduce load on the controller and simplify modulation algorithm. The master controller executes all control and modulation calculations, and the slave controllers manage only device switching and protection. As the core circuit of SST system, DAB converter has wide applications such as battery energy storage device and hybrid electrical vehicles power system.
