Abstract :
This paper shows that the voltage and current harmonics introduced by a single-phase triac ac controller can be significantly reduced by shunting the triac with a fixed-value resistance. Theoretical results are given for a purely resistive load and a fixed RL load with a power factor of 0.7, to substantiate this claim.
