The buck DC/DC converter of Fig. 5 has the following parameters V₁ = 50 V D = 0.4 L = 400 μH C=100 μF f=20 kHz R=202 Assuming ideal components and that the circuit already enters its steady state, calculate: (a) [6] the output voltage Vo, (b) [6] sketch the inductor voltage and current waveforms, (c) [6] the maximum and minimum inductor current, and (d) [6] the output voltage ripple. (e) [9] the RMS value of the capacitor current S iL L + VL VC Dad V₁ Switching duty ratio: D Switching frequency: f Fig. 5. V₁ w R
