Development of Digital Pulse Width ModulationAbstract – DPWM(Digital Pulse Width Modulation) is the key module to digitallycontrolled power converter
DPWM generates necessary switch signal for powercomponents with properties of the ability of integration, high switch signal frequency and stable performance
During past years, based on traditional DPWMstructures, researchers have proposed novel and better structures, which increasesresolution and switch frequency of DPWM
This paper outlines the development of DPWM:firstly, the principles and imple
