Schaltsteuerung einer Betriebsschaltung

摘要

The operating circuit for use with low voltage fluorescent tubes is in the form of a resonating half bridge circuit that has FET devices that act as zero cross over devices. The ac supply is received by a rectifier ÄGLRÜ coupled to the transistors ÄTa,TbÜ and the activation of these is dependent upon the oscillator current and is fixed by the time constant of the control elements. The output of the resonator circuit is applied to the lighting tube ÄKLLÜ.
