Constant Frequency System

In this  system chopping period  T is kept constant but the  on time Tom is varied. This  system is also referred to pulse with modulation or time ration control scheme.

Since we have Vo =Ton /T Vs [from equation by increasing the on time Ton  output  voltage Vo can be increase. This V0  can be varied between zero and source voltage Vs.
