Description
Summary:In this paper, which based on the National High-tech R&D Program of China " design, monitoring, management and protection technology for large-capacity storage system ". it is described that design requirement of the cascaded H-bridge power conversion system, main circuit topology and power unit topology including the way of selecting and confirming the method of the modulation. Key parameters are discussed and power losses are analyzed. Besides, a prototype is built to verify the functions of cascaded H-bridge power conversion system. A series of experiments show that the power control can be achieved flexibly and the SOC balance within one phase and among phases can work with a low harmonic.
