Abstract
A power supply apparatus for electrostatic charging sprayed liquids from a spraying apparatus and method for same, the apparatus including a rotor having a magnet and magnetic poles, a booster coil assembly facing the rotor, for inducing high voltage AC pulses during the rotation of the rotor, and a rectifier for rectifying the high voltage AC pulses induced by the booster coil assembly to high voltage DC pulses and for supplying the high voltage DC pulses to a charging electrode. The power supply apparatus provides a compact and lightweight power generator system, thus eliminating cumbersome operations such as replacement or recharging of a large battery. In addition, a lighter weight and simplified operation reduces the burden on users and facilitates more efficient spraying.
