A method and device for adapting temperatures of semiconductor components. The device includes a first and second semiconductor component, and an evaluation unit. The evaluation unit is configured to ascertain a first and second temperature of the first and second semiconductor component, respectively, calculate a first and second temperature deviation, which represents a deviation of the first and second temperature from a reference temperature, respectively, and adapt a first gate voltage of the first semiconductor component and/or a second gate voltage of the second semiconductor component until the first temperature deviation and the second temperature deviation are smaller than or equal to a predefined maximum allowable temperature deviation from the reference temperature. The adaptation takes place only when a predefined allowable control range for the respective gate voltage is not exceeded, and when the first temperature and/or the second temperature is/are greater than the reference temperature.

Method and device for adapting temperatures of semiconductor components

An electronic circuit unit () comprising at least one electrical or electronic device () with at least one terminal contact (), the at least one terminal contact () being connected in an electrically conducting manner to at least one terminal pad (), at least one terminal contact () and at least one terminal pad () are surrounded in the region of the electrical point of contact by an electrically insulating compound (), the electrical or electronic device () being arranged outside the electrically insulating compound ().

Electronic circuit unit

The invention relates to a method for operating an electric motor () having a phase angle control with the following steps: Applying an AC voltage to a series connection of the electric motor () and a switching element (), particularly a triac, wherein the switching element () connects through by applying an ignition signal and suppresses the flow of a current if the amount of current falls below a holding current; determining the time of a zero crossing of a virtual motor current that would flow if the switching element () were connected through; and turning on the switching element () at an activation time that is dependant on the time of the zero crossing of the virtual motor current.
