摘要：
The three-level converter based on advanced neutral point clamped (A-NPC) topology can improve the quality of the output voltage waveform, decrease the switch voltage and reduce the cost of the insulated gate bipolar transistor (IGBT), and improve the efficiency of the power storage by reducing the loss of the IGBT and inductor. Hence its broad application prospects in the electric power storage domain. The main circuit of the battery power storage converter is designed, the software and hardware of the converter controller are developed, and the control mechanism of the neutral point voltage of the power storage converter is studied. The experimental results of the prototype machine show that the battery power storage converter system based on A-NPC three-level topology built in this paper is fine. Compared with the most common two-level topology, the A-NPC three-level converter is able to have a lower output current waveform distortion factor, lower current harmonics and higher efficiency despite a slight increase of cost. The three-level converter used in the power storage system is able to gain low total harmonic distortion during steady-state operation and excellent efficiency characteristics. © 2015 State Grid Electric Power Research Institute Press.
