ELECTRONIC SELF-BALANCING BALLAST AND METHOD FOR MATCHING A BALLAST

摘要

A DC/AC converter (S1,S2) fed with DC voltage (Vz) generates high-frequency AC voltage (U0) with an output connected to a load circuit (5) including an acceptor circuit and one or more gas discharge lamps (LA). During normal operation of a gas discharge lamp an operating frequency for the AC voltage on the load circuit is constant. A control circuit (1) runs test measurements regarding operating parameters for the load circuit depending on frequency.
