Low cost inverter for EL lamp

摘要: An EL lamp is driven by a flyback inverter having an inductor connected in series with first transistor which switches on and off at high frequency. The junction of the through switching diode to output terminal for connection lamp. A discharge path, including second transistor, coupled removing accumulated charge. low frequency periodically discharging electrical charge In accordance one aspect invention, several diodes are block waste current during another temporarily by-passed provide path either can produce alternating adding capacitor
