In this paper stability and dynamic response analysis of DC-DC buck converter in Continuous Conduction Mode is done through transfer function approach. Also different methods to improve the performance of the converter are analyzed. The transfer function is derived via mathematical modeling of DC-DC buck converter while considering the parasitic effects. Phase margin and gain margin are obtained by plotting the bode plot in the Control toolbox of MATLAB which defines the stability of the system. Step response and impulse response curves are plotted that defines the dynamic behavior of the system. To maintain a healthy balance between the stability and transient behavior improvement a type 3 loop compensation network is proposed since both are indirectly proportional.read more
