Abstract
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.
