The pwm signal plot looks something like as shown in the diagram below. The signal thus produced will have a train of pulses and these pulses will be in form of a square wave. What is sulphation in lead acid batteries sulphation is a process where the sulfuric acid present inside lead acid batteries react with the plates overtime to form layers of white powder like substance over the plates.
We will get into the reason for such a name later.
