Multi-level Bidirectional Power Supply with Fast Response and Its High-precision Voltage Control Method
摘要
Abstract
A high-precision voltage control method for a multi-level bidirectional power supply with fast response is proposed in this paper.The dynamic response speed of the system is effectively improved through the middle- and high-frequency component feedforward of load current, and the severe disturbance of power output voltage under the impact load is reduced. In this way, the anti-interference performance of the multi-level power supply is enhanced. At the same time,the control mode of quasi-proportional resonance(QPR)+repetitive control of voltage loop is put forward,which reali-zes the astatic control of output voltage at the fundamental frequency and the main sub-harmonic frequency.Accordingly, the control precision of output voltage from the multi-level power supply is improved. The proposed control method can effectively improve the system's dynamic response performance and its output voltage control accuracy, as well as enhance the system stability, thus it can be used to solve the reliability problem of power supplies used in the defense facilities and civilian equipment on sea islands.关键词
