Abstract
The present invention discloses a quick start control method and system for a Buck circuit. According to the control method and system provided by the present invention, by controlling a duty ratio of a switch of the Buck circuit within an initial start time period, i.e., a total-on (Ton) time period, at 1, an output voltage can rise at a fastest rate and a capacitor can be charged; and then, by controlling the duty ratio of the switch of the Buck circuit within a Toff time period at 0, the output voltage keeps to rise and simultaneously is stabilized at an expected value. With the adoption of the control method and system provided by the present invention, the overshoot and oscillation caused by the output voltage in a start process of the Buck circuit can be effectively reduced, and the start time of the Buck circuit is shortened.
