成果简介	NOVELTY - The system has a dual-port three-phase converter (DP-TPC) allowed to utilize an embedded e-chopper for minimizing power conversion stages. A minimum voltage port is connected to a battery and regulated by the DP-TPC. A maximum voltage port is controlled through the e-chopper for enhancing operational flexibility. A robust control strategy enables a real-time management process of battery current and dynamic power flows between dual ports and an alternating current grid. Comprehensive experimental results are utilized to demonstrate a stable operation across different voltage levels in a conventional dual-stage systems. A battery is utilized as a back-up source. USE - Quasi single-stage bidirectional DC-AC conversion system for energy storage applications based on bidirectionally mode. ADVANTAGE - The system is provided with low ripple current at the low-voltage side, low current stress on the input inductors, low voltage stress across the switches, high voltage gain and zero voltage soft switching, and offers high efficiency using phase-shift modulation while operating at a nominal design operating point. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a quasi single-stage bidirectional DC-AC conversion system for energy storage applications based on bidirectionally mode.
