Abstract
A boost converter and a power control method thereof. The boost converter includes an inductor, a first switch unit, a second switch unit, a discharging loop and a detecting circuit. The inductor is electrically connected to a power input end. The first switch unit is electrically connected between the inductor and ground. The second switch unit is electrically connected between the inductor and an output end. The discharging loop is connected with the inductor in parallel and includes a third switch unit. The detecting circuit is used to detect a discharging value of the inductor. When the discharging value exceeds a threshold value, the third switch unit is turned on, and the inductor releases energy via the discharging loop.
