Abstract : the initial charge - process of dc capacitor and the steady working state of active voltage - source - inverter power filters are analyzed in this paper , and four new parameters are proposed to judge the working performance of active power filters and to aid their design 文摘:分析了电压逆变器型单相有源电力滤波器直流侧储能电容器的初始充电过程（有源电力滤波器的起动过程）和有源电力滤波器的稳定工作状态，并提出了判定有源电力滤波器性能、帮助有源电力滤波器设计的四个标识性参数。
A new - type buck - boost topology that uses a two - unit ipm as main switching devices to perform charger and depolarizer ; the software / hardware implementation of a dsp ( tms320f240 ) based system controller that performs high - speed data - acquisition , event management , control algorithm and output control -实现基于数字信号处理器tms320f240的充电装置控制电路的软硬件设计，实现高速的数据采集、事件管理、复杂的控制算法和输出控制，从而实现真正高效、快速、无损的充电过程。
The redox of v ( ) / v ( ) , v ( ) / v ( ) couple on the graphite displayed one electron quasi - reversibility . it is proved that trace in3 + , sb3 + can inhibit cathodic hydrogen evolution during the charge process by increasing the hydro - gen overvoltage in addition that sb3 + is a stabilizing / kinetic enhancing ion . during the charge / discharge process , cross - mix and self - discharge rarely happened . the maximal energy density of the lab - level vanadium battery is 21 wh / kg . the capacity efficiency of the lab - level vanadium battery is as high as 94 . 7 % 钒电池充电末期，会发生水的电解反应，痕量铟离子的加入提高了析氢过电位，抑制了充电过程中负极氢气的析出；锑离子的加入不仅可以抑制氢气的析出，还提高了正极反应速率，增强了正极表面的稳定性。实验中得到的最高质量比能量为21wh / kg ，充放电过程中仅有极少的交叉混合和自放电发生，自制钒电池的容量效率可高达94 . 7 %
If one cell fails , the whole battery fails . with use the normal battery management system , the difference between cells enlarge . it " s recommend that a cell management system which embedded a powerful microchip to manage the charge and discharge of cell will solve this problem well 本文分析不一致性对蓄电池使用过程中的影响，试验验证不一致性随着使用次数的增加而增大，造成在充电过程中，充电不均衡，容量未充足的电池在放电中过放电，造成了恶性循环，缩短蓄电池的寿命。
