Abstract

An activation circuit for activating a power bridge circuit of a resonance converter, including an inductive activation transformer that transfers a pulsed control signal generated via a CMOS driver to the power bridge circuit, wherein a clamping circuit is arranged at the output of each CMOS driver, where the clamping circuit clamps a primary winding of the activation transformer to a ground potential during the dead time between two pulses of the pulsed control signal such that overvoltages, which otherwise arise when switching the activation transformer inductance, are thus clamped during a dead time and a circuit breaker switches off securely.
