It is a proportional control method used in inductive and variable resistive loads
(cosØ <1). The disadvantage of this method is that it causes high electrical noise.
It is a control method used in capacitive and variable resistive loads (cosØ =1).
The advantage of this method is that it does not causes high electrical noise.
