High Resolution Digital Duty Cycle Modulation Schemes for Voltage Regulators
2007
IEEE Applied Power Electronics Conference and Exposition. Conference Proceedings
Preserved Fulltext
High switching frequency, high resolution digital pulse-width modulator (DPWM) is one of major challenges in the implementation of digital-controlled power converters, especially in the voltage regulator (VR) application. This paper proposes three different digital duty cycle modulation schemes to improve the resolution. Almost 10 times improvement on resolution can be achieved in the voltage regulator (VR) apparition. Design difficulty of the DPWM can be greatly reduced by proposed modulation
