摘要: A simple and inexpensive dimmable electronic ballast takes advantage of the properties a loosely coupled transformer to control brightness gas discharge lamps. The employs frequency modulation in combination with electrical current through lamps illumination intensity provided by By varying driving signal primary coil powering lamps, can be controlled secondary lamp. is inherent reactance transformer. controlling lamp, light output lamp controllable. plurality may connected true parallel dimming such that failure one does not affect operation remaining Also, high
