Abstract
In an electrostatic sprayer, a pulsating voltage developed using a battery or a generator as a power supply is stepped up using a step-up transformer. A resultant high-voltage pulse is rectified and applied to an electrostatic electrode. A spray jetted from a spray nozzle is thus electrified. Herein, the step-up transformer is located near the spray nozzle. Owing to this structure, a high voltage produced by the step-up transformer can be applied to the electrostatic electrode with a loss minimized.
