Abstract
A driving circuit for electrical nailing gun is disclosed to include a capacitive charging/discharging unit formed of a first resistor, a first diode, and a capacitor connected in series and connected with two opposite ends thereof to the positive and negative poles of AC power source, an excited field unit formed of a first coil and a first electrically-controlled switch connected in series and having two opposite ends connected in parallel to the capacitor, and a control unit electrically connected to the first electrically-controlled switch for activating the first electrically-controlled switch.
