20080290809 | CONTROL CIRCUIT OF A DRIVING CIRCUIT OF A DISCHARGE LAMP - A control circuit controls a driving circuit of a discharge lamp. The driving circuit comprises a half bridge and a clock generator that determines the switching frequency of the half bridge. The control circuit comprises a regulator that regulates the value of the switching frequency when the value of the voltage across the lamp exceeds a threshold value. | 11-27-2008 |
20120169255 | CONTROL DEVICE FOR A DISCHARGE LAMP - A control device of a driving circuit of a discharge lamp is described. The driving circuit comprises an half bridge with a high side and a low side switches and the control device comprises a first device configured to control the switching frequency of the half bridge and a second device configured to detect the saturation current condition of the choke or the over current condition by detecting, cycle by cycle, a signal representative of the current passing through the low side switch. The second device generate a signal to cause the turning off of the low side switch and the turning on of the high side switch when the saturation current or over current condition of the choke is detected. | 07-05-2012 |
