摘要：
A new hysteretic control strategy with output capacitor equivalent series resistance (ESR) ripple compensation is presented. With such compensation, the effect of output capacitor ESR ripple voltage is enhanced. When step load change occurs, feedback of the output ripple adjusts the duty ratio promptly. In result, the proposed control scheme gains faster transient response speed and better steady state than traditional hysteresis without ripple compensation. The steady-state and dynamic operation of the proposed control strategy are analyzed by simulation.
