| 发明名称 | Snubber circuit for a hand held power tool | ||
| 摘要 | A hand held power tool including a trigger, a motor, an output unit driven by the motor, a switch bridge, and a snubber circuit. The switch bridge is operable to selectively provide power to the motor to drive the output unit in response to activation of the trigger. The snubber circuit is electrically connected in parallel across the switch bridge. The snubber circuit is operable to store energy when power is being provided to the motor, and release the energy when power is not being provided to the motor. | ||
