High voltage and low voltage switch mode circuits and methods serve to recover the charge stored on electro-luminescent lamp panels that would otherwise be dissipated during the discharge cycle of a drive circuit. The high voltage circuits and methods operate to transfer the charge to the high voltage rail, while the low voltage circuits and methods operate to transfer the charge to the source of low drive voltage.

Switch mode energy recovery for electro-luminescent lamp panels

Circuits and methods employing the inherent capacitance of an electro-luminescent lamp in a resonant circuit to recover the energy otherwise lost in electro-luminescent lamp driver circuits to thereby increase the overall efficiency of such circuits and to lower the noise and increase the life of the electro-luminescent lamp itself.

Resonant energy recovery for electro-luminescent lamp panels

An EL lamp driver employs constant power regulation rather than pulse frequency modulation to thereby eliminate the high voltage resistive divider network present in prior art EL lamp drivers that employ pulse frequency modulation.
