With the rapid development of power electronics technology and the increasingly widespread application of high-frequency switching power converters in various electronic devices,digital control technology has become a research hotspot due to its excellent performance and flexibility.Through the analysis of the problems caused by Digital Pulse Width Modulation(DPWM)to generate digital duty cycle signals,the limitations of converting analog control signals into digital duty cycle signals are introduced.Based on the Boost converter,a Fuzzy Logic Controller(FLC)of Proportional-Differential(PD)type is proposed,This digital control system can directly generate duty cycles without causing limit cycle oscillation problems,and the effectiveness of the designed controller has been demonstrated through experiments.The research on digital control of high frequency switching power converter aims to provide more precise,flexible,and efficient control solutions for the field of power electronics,and further promote the development of high-frequency switching power converter technology.
