Circuit arrangement |
摘要 |
In a bride circuit comprising a lamp choke that might partially saturate during the ignition of the lamp, at least one of the switches is switched off when the amount of charge displaced through it in forward direction equals a predetermined value. Despite the partial paturation of the lamp choke the amplitude of the ignition voltage is thereby effectively controlled.
