Digital V² Controller for Switching Mode Power Supply

Abstract:

The research interest of this paper is to explore practical ways of incorporating advantages of digital control in Switching Mode Power Supply (SMPS). The two most important issues are the design and implementation of Digital Pulse-Width Modulation (DPWM) and high-performance digital control algorithms for digital controlled SMPS. A Hybrid DPWM method based on digital clock management (DCM) and digital dithering is adopted to generate high-frequency high-resolution PWM. A digital V2 control algorithm is implemented to improve the system performance. The buck converter is studied to analyze the digital V2 control application in SMPS. The simulation and experimental results are presented.
