+ a) In the chopper circuit shown in 2.1, the bidirectional switches S₁ and S₂ are simultaneously turned on for time ton and turned off for time toff = T − ton • where T is the chopping period. Assume voltage v₁ to be ripple-free, and current it to be continuous. i) ii) iii) V S₁ D₁ il + VL D₂ S₂ C Evaluate V. for D = 0; 0.5; 1.0. Figure 2.1 dc-dc converter io Load Derive an expression for V, as a function of the duty cycle D = ton/T and the supply voltage V.
