charging a capacitor的意思|示意

It limits the charging current of each capacitor and also protects the relays in case a capacitor becomes short-circuited.

它限制每个电容器的充电电流，并在电容器发生短路时保护继电器。

While it is charging, a voltage comparator constantly compares the voltage across the capacitor to a reference voltage.

当充电时，一个电压比较器就不断地将通过电容器的电压和一个参照电压进行比较。

This percentage is determined by first charging the capacitor to the rated voltage for a specified time interval, then discharging it for a second time interval.

确定这个百分比的方法是：在一个规定的时间间隔内将电容器充电至某一额定电压，然后在第二个时间间隔内使电容器放电。

Because the capacitor voltage always changes in the course of charging, and the equivalent load also changes in a large range, the load characters of charging circuit are required strictly.

由于电容在充电过程中，其电压不断改变，其等效负载也在较大的范围内变化，因而对充电电路的负载特性提出了较高要求。

R3 limits the charging current of capacitor C3, so that a limited dV/dt exists on capacitor C3 and by consequence also on capacitor C4 which is connected to the IGBT-emitter.

R3限制电容器C3的充电电流，由此在电容器C3上存在受限的dV／dt，并且因此在连接到IGBT发射极的电容器C4上也存在受限的dV／dt。

The diode ACTS like a variable resistance, low when the charging current to the capacitor is high, then increasing in value as the current decreases with time.

该二极管象一个可变的电阻。当电容器的充电电流很大时，其阻值很低；而电流随时间变小时，其阻值增大。
