Control Voltage switched-off 控制电压关闭
Here the discrete on or OFF state of the modulation itself can be used to control the switches thereby controlling the voltage or current across the load.
在这里,离散的开或关的状态调制本身可以被用来控制开关,从而控制得或电流负载。
We can use SPWM to control power tube on or off, can use the double-loop control with the inductance current inner loop and capacitor voltage outer loop is introduced.
可采用SPWM控制功率管的关闭与导通,采用外环电压环,内环电流环的双环控制。
This control method can regulate the burn-off process of contact bridge according to requirements so that the required flashing voltage is lowered and the flashing heating efficiency raised.
这种控制方法可以根据要求改变触点的烧化过程,从而降低激发闪光所需的电压,提高闪光加热效率。
