基于buck变换电路的双闭环超级电容器充电电源，控制器采用PI调节，恒流控制充电，效果良好-Based on buck transform circuit, the double closed loop capacitor charging power supply ，controller PI adjustment, the constant current charge control，The result is good

buck/boost双向DCDC变换电路，即可以进行降压也可升压，采用双闭环控制-buck/boost bi-directional DC DC converter circuit, both can also be buck boost, dual loop control
