Abstract: A low noise H-bridge driver for EL lamps is described herein. The H-bridge controls switching transistors to create an AC voltage across the EL lamp. To reduce audible noise of the EL lamp when driven by an H-bridge, the current through the switching transistors is limited while the voltage across the EL lamp is rising and falling. This reduces the ramp rate of the voltage across the EL lamp and, as a result, reduces vibrations to an inaudible level. The rise time and fall time may each constitute 5%-50% of a half waveform. The rise and fall portions are substantially linear and symmetrical for the half waveform. Current may be limited by using two or more MOSFETs in the H-bridge that have relatively small gate widths.
