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.
