Abstract

Drivers or ballasts for ultraviolet lamps of water treatment systems. Which the driver said Will be included Higher current transformer And feedback oscillators Connected between the secondary winding and the primary winding of the transformer. The secondary winding of such a transformer It is also selected through one of two different capacitive compensators. Depending on the water flowing through the system In low intensity conditions Current and output power factor of that driver It is low enough to keep the filament of the lamp energized. In conditions of high intensity The current and the power factor are high to power the lamp to operate at high. The driver operates at a low DC voltage level. Will be selected to work depending on the voltage sent along the line. Which converts the AC electrical level to the desired DC voltage.
