The proposed inverter has a new auxiliary resonant commutation cell. It provides that all main switching power devices in the soft-switching inverter operate at zero-voltage-switching turned-on and the auxiliary switches operate at zero-current-switching turned-off.

Because of the extremely short discharge times, currents of several tens of thousands of amperes are obtained, causing the coil to produce and enormously powerful increasing magnetic field, which, on passing through the disk, induces a current on it. Due to the turns ratio (16 turns coil - 1turn disk), the current through the disk is several times greater than that through the coil.

由于是极短的时间，这样就会获得几万A的电流，使线圈产生极大的磁场穿过铝盘，产生涡流，按照匝比计算（线圈16匝，铝盘1匝），铝盘上的电流是几倍于线圈。

In addition it can real time watching and controlling what will be change about the temperature、the current and the voltage which belong to the electrification equipment.moreover it could take the com port and the umb communicate,later show the information to user.there is action that is dummy instrument.otherwise ,it can also change parameter,and suit different charger.

充电器可以实时采集电池的电压、电流，对充电过程进行智能控制，计算电池已充的电量和剩余的充电时间；并实时监控充电器材的温度、电流和电压大小以便调控充电进程，还可以通过串口和上位机进行通讯并给用户显示必要的信息，有虚拟仪表的作用；另外，它也可以改变参数，适应各种不同电池的充电。

In addition, this circuit slightly reduces the current drain in active mode by eliminating current flow through the unactuated switch.

此外，电路通过未激励开关消除电流的方法，从而略微减少了现有模式中的电流消耗。

A state variable feedback based system control approach, which indirectly controls load voltage by means of controlling the supply current, is proposed, thus the problem that the undamped DC transient component of supply current, which is caused by the linking inductance between power supply and power loads under PI control mode, is solved.

分析了仅由1套逆变器构成的并联型综合电能质量调节器的结构特点和控制目标，提出了一种基于状态变量反馈的系统控制方法，通过控制电源电流来间接控制负载电压，很好地解决了常规比例–积分控制时电源和负载间的连接电感所导致的供电电流直流暂态分量不衰减的问题。

Unfortunately, there is inevitably difference in characteristics of the induction motors and converters in a parallel AC drive system, therefore each induction motor as well as converter can not operate at the same working point, some may be overload, some underload.

并联着的各个交流调速系统的负载是不均衡的，这是因为逆变器所带的负载—异步电动机参数及特性不可避免地存在差异，两或多台逆变器作为电源，其等效参数也很难一致，各驱动轮径总存在偏差，因此各台逆变器的输出电流和各台异步电动机的定子电流是不相一致的，有的逆变器、异步电动机可能过载，有的还可能欠载。

In the modelling aspect, Boeuf and Garrigues have established the transient state unidimensional quasi-neutrality combination model, has calculated the electron current and ion electric current vibration [1] separately.

在建模方面，Boeuf 和Garrigues建立了瞬态的一维准中性混杂模型，分别计算了电子电流和离子电流的振荡[1]。
