Abstract: The present disclosure relates to an electric circuit system. The system includes a housing, a printed circuit board mounted within the housing, an electric component conductively mounted to the printed circuit board, and a cooling system for transferring heat away from of the electric component. The printed circuit board is compartmentalizing the inside of the housing into a first compartment and a second compartment, and the electric component is situated in the first compartment. The cooling system includes at least one first heat transferring element located adjacent to the electric component. The at least one first heat transferring element is secured to the housing surrounding the second compartment capable of forming a heat flowing path defined to transfer heat from the electric component to the housing via the at least one first heat transferring element.

Abstract: An AC-DC converter device includes a first overvoltage protection circuit connected between a first DC output terminal and a first control terminal of a gate pulse controller. The first overvoltage protection circuit is configured to turn off a first switch if the output voltage between the DC output terminals is above a threshold voltage. A galvanic insulation barrier is connected either between the first overvoltage protection circuit and the first control terminal or between the first control terminal and the first switch.
