An adaptive pre-charge control circuit includes include a high-voltage switch and a control circuit. The high-voltage switch controls the flow of current between an electric battery and a DC link capacitor, the electric battery to supply power to an electric vehicle. The DC link capacitor is made up of a sum of individual input capacitors of multiple subunits within an electric vehicle. The control circuit sends a PWM signal to the high-voltage switch based on a difference between an electric battery voltage and a DC link capacitor voltage.

A method for producing a semiconductor device includes providing a carrier configured to carry at least one semiconductor chip on a first side, and dispensing a polymer onto a second side situated opposite the first side in order to produce a sealing ring. The polymer is dispensed in such a way that the sealing ring produced has different heights perpendicular to the second side along its circumference.
