Abstract
According to the present invention an electronic stabilizer circuit for suppressing startup instabilities when supplying a cold cathode fluorescent lamp with current is proposed which is connected in series with a power supply line of the cold cathode fluorescent lamp. The stabilizer circuit has variable impedance which is automatically adjusted depending on the magnitude of the lamp current thus limiting the lamp current to a certain current threshold.
