摘要 双向DC/DC转换器是实现高低压电能双向传输功能的直流转换器,在各种直流稳压电源设计上应用广泛。通过小信号分析法,将非线性的DC/DC转换器变换为线性的数学模型进行研究,确定了全桥DC/DC转换器在升/降压模式下的传递函数,然后通过离散型PID控制算法,分析了系统控制的稳定性并确定了PID参数,设计了转换器补偿网络。最后通过仿真模型和样机实验验证,证明了双向全桥DC/DC转换器的升/降压控制系统的有效性。 The bidirectional DC/DC converter can realize the high voltage and low voltage bidirectional conversion, and is widely used in the design of various DC voltage-stabilized power supply. The nonlinear DC/DC converter is transformed into the linear mathematical model by means of the small signal analysis method for study. The transfer functions of full-bridge DC/DC converter in Boost/Buck modes are determined. And then the discrete PID control algorithm is used to analyze the stability of the control system and determine the PID parameters. The compensation network of the converter was designed. The simulation model and prototype experiment were verified, and the results show that the Boost-Buck control system of the bidirectional full-bridge DC/DC converter is effective.
