Abstract

A BALLAST CIRCUIT (103) IS DISCLOSED FOR INDUCTIVELY PROVIDING POWER TO A LOAD. THE BALLAST CIRCUIT (103) INCLUDES AN OSCILLATOR (144), A DRIVER (146), A SWITCHING CIRCUIT (148), A RESONANT TANK CIRCUIT (150) AND A CURRENT SENSING CIRCUIT (218). THE CURRENT SENSING CIRCUIT (218) PROVIDES A CURRENT FEEDBACK SIGNAL TO THE OSCILLATOR (144) THAT IS REPRESENTATIVE OF THE CURRENT IN THE RESONANT TANK CIRCUIT (150). THE CURRENT FEEDBACK SIGNAL DRIVES THE FREQUENCY OF THE BALLAST CIRCUIT (103) CAUSING THE BALLAST CIRCUIT (103) TO SEEK RESONANCE. THE BALLAST CIRCUIT (103) PREFERABLY INCLUDES A CURRENT LIMIT CIRCUIT (700) THAT IS INDUCTIVELY COUPLED TO THE RESONANT TANK CIRCUIT (150). THE CURRENT LIMIT CIRCUIT (700) DISABLES THE BALLAST CIRCUIT (103) WHEN THE CURRENT IN THE BALLAST CIRCUIT (103) EXCEEDS A PREDETERMINED THRESHOLD OR FALLS OUTS IDEA PREDETERMINED RANGE.
