Research on a FPGA based Digital PWM Controller for DC/DC Converters

A novel way of digital Pulse Width Modulation(PWM) controller with high-frequency and high precision based on Field Programmable Gate Array(FPGA) is described in this paper.The digital PWM controller is implemented on FPGA and the functions of digital PWM controller are analyzed.The digital controller implementation is proposed and the experiment verified on the prototype Sync-Buck 12V input 1V output VR.
