摘要
当负载功率脉动性变化时,蓄电池会产生较大的峰值输出电流。这会对端电压与寿命造成严重影响。本文结合超级电容器与蓄电池,设计了一种新结构的复合电源。通过电路仿真,校正了PID控制参数,验证了控制电路的有效性。搭建了复合电源样机,得出了复合电源在带功率脉动性负载时,相对蓄电池或超级电容器的应用优势。
When load power is pulsating,the accumulator would provide a large output current.This can seriously impact output voltage and battery life.Combined with an accumulator and a super-capacitor,a new structure of hybrid power system was designed.Using circuit simulation,PID parameters were determined,and the validity of the control circuit was verified.A modular power supply was built,and experiments prove the hybrid power system has application advantages in driving pulsating loads compared with accumulators or super-capacitors alone.
