  • Electroluminescent lamp driver
    Patent number: 5066895
    Abstract: A driver for a electroluminous lamp includes a bridge switching circuit comprising four MOSFETS, the lamp and a series connected inductance being connected as the load on the bridge circuit. The switching of the transistors of the bridge circuit is controlled by logic circuitry which generates a two-phase, non-overlapping gating control signal which causes the MOSFETS to be switched in pairs whereby current will flow in alternate directions through the lamp.
