Circuit arrangement with a resonance converter and method for operating a resonance converter

摘要

The circuit device (28) has a short-circuit monitoring unit (30) for protecting the semiconductor components of a resonance transducer (12). A resonance error controlling unit (31) is formed on the resonance region for the shutdown of the resonance transducer with the detection of the approximation of the operation of the resonance transducer. A resonance trend detection unit (32) is arranged for adjustment of the frequency of the resonance transducer to compensate the approximation of the operation of the resonance transducer to the resonance region. An independent claim is included for a method for operating resonance transducer.
