Abstract :
A new PWM hysteresis control with feedforward and feedback for buck converter is presented. The proposed control scheme is based on hysteretic control of capacitor C voltage, which offers better fast transient response and better stability. The steady-state and dynamic analysis of the control scheme is performed and verified by simulation and experiment results.
