Abstract (en)
[origin: EP0127101A1] 1. An inverter comprising two switches (T1, T2) which can be alternately rendered conductive, and comprising a load circuit arranged parallel to the first switch (T1) and connected via the second switch (T2) to a d. c. voltage source (Q), and consisting of the series arrangement of a reversible oscillatory capacitor (C10), a series resonant circuit composed of a choke (L1) and a capacitor (C9), and a discharge lamp (LP) equipped with heatable electrodes, where these electrodes are arranged in the load circuit and are connected to one another via the capacitor (C9) of the series resonant circuit, and comprising a control set (S) which supplies control voltages which alternately render the switches conductive, characterised by a burning voltage sensor (B) which monitors the burning voltage of the lamp (LP) and supplies an output signal dependent upon the burning voltage and fed to the control set (S) to determine the frequency of the control voltages which it supplies.
