Abstract (en)
[origin: EP0710052A1] The starter includes the electronic switch in parallel with the lamp fed at high voltage, the grid control circuit (5) for the power switch (3), having a measuring circuit for a set pre-heating time, and an auxiliary supply circuit (AUX) in parallel with the switch (3). The auxiliary circuit (AUX) includes a capacitor (C), which supplies a logic voltage (Vdd) to the control circuit (5) from a terminal (c1) of the capacitor. The pre-heating time measuring circuit includes a comparator. The comparator compares the voltage on the terminal (c1) to a first reference voltage, so as to deliver a detection signal at the start of pre-heating to control the closing of the switch (3) and to a second reference voltage, so as to deliver a preheating end signal to control opening of the switch (3).
