Abstract
A power tool that includes a motor configured to drive a working element, a power supply that is coupled to the motor to provide power to the motor, a shunt circuit that is coupled to the power supply and the motor, and a controller. The shunt circuit includes a shunt switch and a shunt element and is configured to hold a voltage of the power supply below a high voltage threshold. The shunt switch is switchable between a conducting state, in which the shunt switch conducts current through the shunt element, and a non-conducting state, in which the shunt switch does not conduct current through the shunt element. The controller is coupled to the motor, the power supply, and the shunt circuit and is configured to determine the voltage of the power supply, and control the shunt switch based on the voltage from the power supply.
