【摘要】：旨在设计一款单向、非隔离、降压型的宽范围输出电压电池充电调节器(Battery Charge Regulator,BCR),作为卫星电源系统母线至蓄电池的充电通路。选择耦合电感Superbuck变换器作为电池充电调节器的主拓扑。分析变换器工作原理后,得到耦合电感的零输入电流纹波条件,推导出系统开环传递函数;得到避免右半平面零点出现的阻尼参数限制条件。根据先恒流后恒压的充电控制策略,选择平均电流控制模式作为变换器控制方式,在恒流充电阶段,仅电流内环工作,变换器工作在电流源状态;恒压充电阶段,利用平均电流模式的双环控制特点,变换器工作在电压源状态。通过仿真和实验结果验证了设计的正确性。
[Abstract]:The aim of this paper is to design a unidirectional, non-isolated, step-down type battery charging regulator with a wide range of output voltage, Battery charge regulator (BCR), which can be used as the charging path from the bus of the satellite power system to the battery. The coupling inductance Superbuck converter is selected as the main topology of the battery charging regulator. After analyzing the principle of the converter, the zero-input current ripple condition of the coupling inductor is obtained, the open loop transfer function of the system is derived, and the damping parameter limiting condition is obtained to avoid the zero point in the right half plane. According to the charging control strategy of constant current and then constant voltage, the average current control mode is chosen as the control mode of the converter. In the constant current charging stage, only the current inner loop works, the converter works in the current source state, and the constant voltage charging stage, Using the dual loop control characteristic of average current mode, the converter works in the voltage source state. The correctness of the design is verified by simulation and experimental results.
