Abstract
A power tool includes a direct current (DC) unit, a motor, a driving circuit, a capacitor circuit, and a control unit. The capacitor circuit includes a switching element and a capacitor. The control unit drives the switching element to realize the control of charging or discharging of the capacitor. The capacitor circuit is connected between the DC unit and the driving circuit, and can buffer the impact on the power supply side of the power tool, making the power tool compact in structure.
