Abstract

A new digital control scheme aiming to improve the transient response of an FPGA-based digitally controlled DC-DC converters is presented in this paper. The proposed approach enhances the transient response by dynamically controlling the ramp of the Digital Pulse Width Modulator (DPWM) unit through applying either linear or nonlinear shift to the conventional ramp-based DPWM. This allows the compensator to reach steady-state faster. The advantages and disadvantages of both techniques are presented and weight against improvement on transient response. Detailed analysis, simulation results and experimental waveforms are presented to verify the concept. © 2010 IEEE.
