Abstract

Based on inductor current ripple and output voltage ripple to charge and discharge for capacitor C, a fast hysteresis control strategy is proposed in this paper. It is not only simple and solves the compensation problem of the error amplifier in conventional voltage PWM control, but also provides better transient response and stability to meet the challenges of the buck converter. Finally, the steady-state operation of the proposed control strategy is analyzed and verified by simulation and experimental results.
