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.
To improve the behaviors of DC-DC converters, a hysteresis control strategy with inductor current feedback is put forward. The output voltage, output of hysteresis comparator and inductor current are messured to control the capacitor voltage, the value of the capacitor voltage and the hysteresis band width are calculated, and the capacitor voltage is controlled to a narrow range around the hysteresis...
