- In the chopper circuit shown in figure.4 the innut de voltage

- In the chopper circuit shown in figure.4 the innut de voltage has a constant value Vs, the outpul voitage sumed ripple free. The switch S is operated with a switching time period T and a duty ratio D. What is the value of D (based on L,R and T at the boundary of continuous and dissentious conduction mode of the inductor current iL. (20 points) + VL - Is L Vs Figure 4
