1. Design a buck converter and a resistive load operating in CCM mode with the following specifications: 0.5 %, Vin = 20 V, f =30 kHz, Duty cycle d=0.4, and R =5.33 №. Determine (AV%) = Vo (a) the output voltage and current of the buck converter. (b) the Critical (minimum) inductance for CCM mode (c) select L currents. = 600 μH and find the maximum IL,max and the minimum IL,min inductor (AV) Vo (d) find the capacitor value that corresponds to = 0.5% for this buck converter (e) redesign the circuit above to achieve an output ripple voltage of 1 % and an inductor cur- rent ripple 10 % at the average load current with the same Duty cycle d, frequency, load Resistance, and Vin. Calculate the accepted new L and C.
