| Zusammenfassung: | The device has voltage and power measuring circuits, where a measurement signal is proportional to a voltage at a discharge and another measuring signal is proportional to a current flowing through the discharge lamp. A combination of analog and digital circuits is used for evaluation of energy, which is coupled into the lamp during high voltage impulse, from voltage and current signals. A comparator is provided to output a signal from the adjustable threshold voltage. A detection device is provided for detecting the high voltage impulse. |
