正负脉冲式高频开关电源的研究

针对电池在充电过程中，电池内部产生的气体严重影响电池的使用寿命和容量的情况，提出了在充电过程中，可以通过瞬间放电把电池内部的气体排出的正负脉冲式充电方法。给出了正负脉冲式高频开关电源的电路拓扑结构及控制方法，采用新技术提高系统的功率因数。通过试验验证了该方法在提高电池有效容量和缩短电池充电时间方面有了明显的改善。

Study of high-frequency switching power supply with positive and negative pulsing

In battery charging process,the gas produced in the internal battery seriously affects the battery life and capacity.This paper proposes a positive and negative pulse charging method,with which the gas is exhausted inside the battery through the instantaneous discharging in the charging process.It gives the positive and negative pulsed high-frequency switching power supply circuit topology and control methods.It uses new technology to improve the power factor.The method improves significantly the battery ca...
