What is the purpose of forced commutation in SCR applications? Answer : The purpose of forced commutation in SCR (Silicon-Controlled Rectifier) applications is to turn off the SCR before the current through it naturally drops to zero. In SCRs, once they are turned on (by ... off the SCR by forcing the current to zero, enabling it to be turned on again when needed....
