DC-DC Power Regulator Design

Steve Hung-Lung Tu

Abstract

This chapter presents a comprehensive introduction and fundamentals of design techniques for switching-mode digital pulse-width modulation (DPWM) power regulators. The presented switching-mode regulation approach inspires several novel building functional blocks such as error process unit (EPU), multipleaccess table look-up based PID compensator, and multi-phase digital PWM. Compared with the conventional architecture with an analog-to-digital converter, the new switching-mode configuration can reduce the system complexity. The practical considerations for the implementation will be presented in the case study concerned with a fully table look-up digital PWM controller for high-frequency power regulation.
