由于阶梯充电效率高,人们颇感兴趣.若阶梯数为N,那么每次充电就由N步充电来完成.设每个阶梯电压为V_0,则在储能电容上得到的电压间隔也为V_0.由于电压不能连续调节,给实际应用带来了一定的困难.为了克服此种缺点,我们对阶梯充电电源进行了改进,给出了一种电压连续可调的阶梯充电电源的原理及实现途径. Because of the high efficiency of the ladder charge, people are quite interested.If the number of steps is N, then each charge is completed by charging N steps.Each step voltage is V_0, then the voltage across the storage capacitor is also V_0 Because the voltage can not be adjusted continuously, it brings certain difficulties to the practical application.In order to overcome these shortcomings, we improved the stepper charging power supply and gave a principle and realization way of the stepwise charging power supply with continuously adjustable voltage .
