摘要
设计了一种基于MSP430单片机的电动自行车充电器软硬件,讨论了该充电器的充电控制策略。所设计的充电器分段采用电压、电流反馈,根据期望值和反馈值的偏差采用PID算法对PWM的占空比进行调节,以实现分段恒压恒流的充电控制。
This paper designs the hardware and software of electric bike charger based on MSP430 Microprocessor and discusses the charging control strategy of the charger. This paper uses voltage and current feedback in the charger design and uses PID algorithm to adjust the duty cycle of the PWM in accordance with the deviation of the expected value and feedback value,in order to achieve the charging control of sub-constant voltage and current.
