Control and Modeling of High-Frequency Voltage Regulator Modules for Microprocessor Application
… to meet the VRM specifications is studied. The sigma converter is proposed for the 48V VRM solution due to exhibition of high efficiency and high-power density from hardware evaluation. An accurate model for the sigma converter is derived using the new modeling approach of modularizing the small …
