摘要
In this paper, an improved hysteretic PWM control with feed-forward and feedback for the buck converter is presented. The proposed control method is based on hysteretic control of capacitor C voltage, which not only offers faster transient response to meet the challenges of the power supply requirements of fast dynamic input and load changes, but also provides better stability and solves the compensation problem of the error amplifier in the conversional voltage PWM control. Finally, the steady-state operation of the control method is analyzed and verified by the simulation and experimental results.
