At least one fastening element attaches the at least one circuit board to the circuit board support through an engagement with the circuit board support, wherein the capping is formed and/or attached to the base in such a manner that room is formed between the fastening element and the capping in such a manner that a detachment of the fastening element from the circuit board support is prevented.

Housing with electronic components

A method for voltage balancing of series connected capacitors, wherein a voltage in an intermediate circuit of an electric circuit can be easily and safely balanced between a plurality of series connected capacitors and thus these components are operated safely in terms of their voltage strength. This problem is solved in that the voltage balancing is accomplished in that, in a first step of the method, an at least partial discharging of a first or a second capacitor occurs across a first or second winding of a transformer, while thanks to the action of the transformer a current is induced in a second step of the method in the second or first winding which charges the second or first capacitor as a charging current.

Disclosed herein is a power electronic device assembly for preventing parasitic switching-on of a feeder circuit breaker. The assembly includes a logic circuit, a power switch with an input and a reference leg, and a driver circuit which drives the power switch. The driver circuit includes a drive unit and a short circuit having a safety function. When the input of the power switch is not operated, the power switch is short-circuited by the reference leg so that the potential of the input decreases below a switching-on threshold. An additional wire connection device is disposed between the driver circuit and the power switch and configured such that when no or excessively small amount of supply voltage is applied, the input of the power switch is short-circuited or is coupled to a safety potential at which discharge is secured, whereby discharge of parasitic charge current is secured.
