= 4. A Buck converter has the following parameters and is operating in CCM: L = 100 pH, C = 700uF; r = 0.10;fs = 100 kHz, Vin = 30V, and P. = 36W. The duty ratio D is adjusted to regulate the output voltage Vo = 12V The Pspice simulation showed that at the crossover frequency fc = 1 kHz, the power stage has Gps(= 24.66 dB and 2Gps(8), Design the feedback controller for this Buck converter such that the output voltage sensing network in the feedback path has again of kpe = 0.2. The steady state error is required to be zero and the phase margin of the loop transfer function should be 60" at, as high a crossover frequency as possible = :-138 KFR (s) = 0+ ) dis) Power Stage Σ Controller 7.)
