Abstract: In this paper, the control model for a digitally controlled DC-DC converter is presented along with derivative filter. The digital implementation of this model gives the detailed description about the gain and phase responses of each block in the digital controller loop. Key problems such as quantization resolution of digital pulse width modulator (DPWM), steady state limit cycle oscillations and loop delay of the controller are discussed and solutions are presented. The controller is implemented in an altera Quartus II 9.0 tool and simulated with an inbuilt simulator. It is observed that the controller utilizes less resource and consumes less power, means that the controller cost can be reduced. �2010 IEEE.
