Abstract
A power tool includes a power a motor, a driver circuit, a capacitor, a capacitor switch, a temperature detection unit, and a controller. The capacitor is configured to filter out current spikes in a power supply. The capacitor switch is configured to control a working state of the capacitor. The temperature detection unit is configured to detect a temperature of a related object. The controller is configured to: acquire the temperature of the related object; control the capacitor switch to be in a first on or off state such that the capacitor works in a first working state when the temperature is lower than a temperature threshold; and control the capacitor switch to be in a second on or off state such that the capacitor works in a second working state when the temperature is higher than the temperature threshold.
