Webb4 mars 2024 · SCR Drives (Silicon Controlled Rectifier Drive) are almost always DC. A motor drive controls the speed, torque, direction and resulting horsepower of a motor. AC drives control AC induction motors, and-like their DC counterparts-control speed, torque, and horsepower. WebbThe techniques to turn off a SCR can be broadly classified as • Natural Commutation • Forced Commutation. 5.1.1 Natural Commutation (CLASS F) This type of commutation takes place when supply voltage is AC, because a negative voltage will appear across the SCR in the negative half cycle of the supply voltage and the SCR turns off by itself. Webbturning on the SCRs, because this method lends itself ac-curately for turning the SCR at the desired instant of time. In addition, gate triggering is an eficient and reliable method.[1] The gate control circuit is also called iring, or triggering cir-cuit.
