A dc-dc converter is used in rheostatic braking of a dc series motor, as shown in Figure 14.17. The armature resistance Ra=0.04 Ωand the field resistance Rf=0.04 Ω. The braking resistor Rb=5 Ω. The back emf constant Kv=14 mV / A rad / s. The average armature current is maintained constant at Ia=200  A. The armature current is continuous and has negligible ripple. If the duty cycle of the dc-dc converter is 60 %, determine (a) the average voltage across the dc-dc converter Vch; (b) the power diss
