Abstract: A method for braking a power tool, wherein the power tool has a motor which is connected to an output shaft via a belt drive, wherein the method includes the following steps: a) applying or maintaining a braking torque, acting on the motor, for a first period of time; b) reducing the braking torque for a second period of time; c) increasing or maintaining the braking torque for a third period of time.

Abstract: A method for braking a power tool (10) is provided, the power tool (10) being a battery-operated or mains-operated power tool and including a brake chopper, and at least pert of the electrical energy that is released when the power tool (10) is braked being fed back to a power supply device (14) or a DC link of the power tool (10).

Abstract: A mains-operable power tool having a mains connection, a rectifier connected downstream of the mains connection, and an electric motor with an upstream motor stage, wherein the rectifier and the motor stage are connected via an intermediate circuit having a smoothing capacitor connected in parallel with the rectifier and a switching branch connected in parallel with the rectifier, wherein the switching branch has an additional capacitor which can be discharged if necessary via a discharge circuit included in the intermediate circuit by a switching element included in the switching branch, wherein the intermediate circuit has a precharge circuit which is or can be used to set an offset voltage of the additional capacitor.

Abstract: A circuit is proposed comprising (i) a first switching path comprising at least one electronic switch, wherein the first switching path can turn off in both directions and can turn on in both directions, and (ii) a second switching path comprising two electronic switches and at least one capacitance, wherein one diode path per electronic switch is embodied in parallel with the electronic switch or in series with the electronic switch. Additionally, a method for operating such a circuit is specified.
