摘要
以双半桥拓扑为基础,提出了一种基于脉宽与相位混合调节的控制策略,实现对蓄电池的充电和LED灯的恒流控制。分析了该控制系统的电路拓扑、工作模式和控制策略等,最后制作了一台试验样机验证了该控制策略的可行性。
On the basis of the double-bridge buck-boost topology,a control strategy based on pulse width and phase mixing adjustment is proposed to realize the charging of the battery and the constant current control of the LED.The circuit topology,working mode and control strategy of the control system were analyzed.Finally,a test prototype was made to verify the feasibility of the control strategy.
