Abstract:
An electrostatic painting device capable of reducing any AC or electromagnetic emissions when the device is powered on is provided. The emissions affect electronic components present during painting of various objects or even when the device is powered on. The electromagnetic induction into the conductive circuit elements in turn induces voltages and currents, which potentially harm the micro-electronic circuits. One such device includes a choke between a fluid tip and a high voltage source of the device to reduce these emissions. The voltage source may include at least one capacitor which supplies the AC emissions representing electromagnetic emissions risk during the discharge of paint from the device. The choke connected to the voltage source substantially reduces the emissions involved during the paint discharge, while allowing the discharge of electrons, thereby imparting negative DC charge to the paint and the workpiece, and preventing damage to electronic circuits during the process.
