Abstract

A compact DC/AC inverter for a large electroluminescent (EL) lamp is presented and experimentally studied. The inverter topology based on the push-pull inverter, and its operations are similar to that of the flyback converter. The DC input voltage is converted to a high frequency AC voltage by the push-pull inverter at a switching frequency of 50 kHz and then rectified to AC 200 Vp-p/500 Hz by the bi-directional synchronous switch. By using this technique, HVDC capacitor, high side switch gate-drive transformers and rectifier diodes are not required. The measured efficiency when the inverter was loaded by 193.34 inch² EL lamp is about 78% at an output power 4.8 W
