QUESTION 2 [35 Marks] 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) iv) V S₁ D₁ + 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. 333 V Sketch the waveforms of Vo.VL. IL. io and is for D = Discuss the advantages and disadvantages of this circuit? [3 Marks] [2 marks] [5 Marks] [2 marks]
