You have to design a closed loop controlled buck converter, as shown in Fig. 1. VIN IM S Ge(s) Fig. 1 The converter has the following specifications: Input DC voltage (VIN): 12 V Average output voltage (VOUT): 5 V Switching frequency (f): 200 kHz Load current: 1 A Peak-to-peak inductor current ripple: 10% Peak-to-peak capacitor voltage ripple: 0.25% Reference voltage for controller (Vref): 3.3 V Peak voltage of triangular carrier in modulator (VM): 3.3 V Vout Vref (a) Determine the required values of inductance L and capacitance C. (b) Determine the feedback gain H and the gain provided by the modulator. (c) Show Bode plot (magnitude and phase) of the uncompensated loop gain (Tu) generated using Matlab. What are the magnitude and phase of the loop gain at 20 kHz? [5] [5] [5]
