Abstract

The invention discloses a high-frequency electronic ballast. The high-frequency electronic ballast comprises a capacitor C1, a capacitor C3, a diode D2, a capacitor C12, a transformer T1, a transformer T2, a chip KA7543, a resistor R2, a resistor R3, a lamp tube Rp, a starter C, a resistor R8, a low-frequency oscillator B and a potentiometer R4, wherein a tenth pin of the chip KA7543 is connected with one end of the capacitor C3; the other end of the capacitor C3 is connected with the ground end of a power supply A; an eleventh pin of the chip KA7543 is connected with one end of a capacitor C4. The high-frequency electronic ballast has the advantages that the constant power output of an HID (High Intensity Discharge) lamp is achieved by driving an MOS (Metal Oxide Semiconductor) through the chip KA7543 and a voltage-controlled oscillator similar to an IC (Integrated Circuit), and the energy consumption is greatly reduced.

Description

technical field [0001] The invention relates to a ballast, in particular to an electronic high-frequency ballast. Background technique [0002] There are many literatures on high-frequency electronic ballasts for HID lamps, and there are various products, but few of them are really practical. The available ones are expensive, so low-frequency square wave electronic ballasts appear again. To solve the acoustic resonance of the lamp current when it works at high frequency. Acoustic resonance is solved, but its own power consumption is nearly doubled, which is almost equal to the power consumption of magnetic ballast itself, and the energy-saving efficiency is reduced. Contents of the invention [0003] The object of the present invention is to provide an electronic high-frequency ballast with good energy-saving effect, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the f...
