ACTIVATION CIRCUIT OF A RESONANCE CONVERTER |
摘要 |
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. |

1. An activation circuit for activating a power bridge circuit of a resonance converter, comprising:
a plurality of CMOS drivers; an inductive activation transformer which transfers a pulsed control signal generated via the plurality of CMOS drivers to the power bridge circuit; a clamping circuit arranged at an output of each CMOS driver of said plurality of CMOS drivers, said clamping circuit clamping a primary winding of the inductive activation transformer to a ground potential during a dead time between two pulses of the pulsed control signal. |
