Abstract
A method and an activation circuit for frequency generation for a resonance converter that is driven by a half bridge or a full bridge. An activation circuit with a controller excites a resonance circuit belonging to the resonance converter. The power, current or voltage of the resonance converter is controlled via the frequency. The controller activates a programmable variable clock generator via a first interface. The frequency dividers able to be programmed via a second interface create the operating frequency of the half bridge or full bridge by dividing the frequency of a clock generator into different duty cycles. The frequency of the clock generator amounts to a multiple of the bridge frequency, and the second clock generator and thereby the H-bridge frequency of the resonance converter is independent of the first clock generator which supplies the controller.
