Buck - Boost DCM converter, ACM model!
P_out= 5-30 W
V_in= 18-32 V
V_out= -24 V
Voltage controller = PI
Current controller = PI
show in matlab bode = T, H_DR , H_T , in all working range, and other bode if needed
Show PSIM and simulations
all explanation on file , average current model (ACM), ac small signal model,
