ELECTRONIC STABILIZER FOR DISCHARGE LAMP AND DIMMING METHOD

摘要

This ballast consists of a high frequency oscillator which is connected to the DC power sources in order to regulate the current and stabilize. The oscillator consists of two transistors which are connected to the base driving transformer in series in order to operate in the phase, and the resonant circuit which is consisted of a resonant capacitor and a inductor with a capacitor which is connected to the lamp in parallel and the circuit connecting to the primary winding of a transformer in series. The lamp is connected to the resonant circuit in series. The purpose of this ballast provides the ballast which eliminates the high frequency interference and reduces the electric loss in the filter capacitor.
