4. The Boost converter is shown in figure, the transfer function of controller is \( G_{c}(s)=250 / s \), then \( (25 \) points) (1) Please describe the Bode curve of loop-gain transfer function \( T(s) \); (2) Given the value of crossover frequency and phase margin; (3) Describe the Bode curve of transfer function \( 1 /(1+T(s)) \);
