Abstract: A voltage changer (VC) (12) generates a wired VC output voltage (Uw). A transformer (14) fed on its primary side by the VC connects a load output (24) to its secondary side. A resonance capacitor (Cr) forms a resonance layout with leakage inductance for the transformer and/or an external inductance. A test device (16) determines operating parameters for a power supply system. A current sensor (22) measures current (ir) on the primary side of the transformer. An Independent claim is also included for a method for determining operating parameters for a power supply system.

Abstract: The discharge lamp comprises a piezotransformer and at least one of the lamp electrodes comprises a secondary side of the piezotransformer. Since the piezotransformer functions as a lamp electrode, as a ballast choke and as a transformer, the discharge lamp can be operated by means of a relatively simple and cheap ballast circuit.
