Generalized Type III controller design interface for DC-DC converters

In this paper, a generalized Type III controller design interface for DC-DC converters is built and presented in order to calculate the compensator parameter values in a more convenient and fast way. When the specifications of the DC-DC converter (buck, boost, buck-boost, etc.) are input to the MATLAB design interface, the corresponding parameters values (resistors and capacitors) of the Type III compensator and the bode plot of the DC-DC converter open loop gain can be obtained. By designing the Type III controller though this interface, the DC-DC converter can obtain stable and fast transient response performances with small steady state error. Finally, simulation results using 65-nm CMOS technology are presented to verify the developed generalized Type III controller design interface for different DC-DC converters.
