The invention relates to an EMC filter for a control device. The filter includes a multilayer circuit carrier comprising electrically conductive layers, in particular copper layers, and electrically insulating circuit board layers. According to the invention, the circuit carrier of the aforementioned type forms at least two filter capacitors, wherein in each case the filter capacitors are formed by electrically conductive layers that are formed in the circuit carrier and lie across from one another and/or extend parallel at a distance from each other.

EMC filter for a control device

The arrangement relates to a voltage transformer for transformation between a direct voltage at a direct voltage gate and a single-phase or multi-phase alternating voltage at an alternating voltage gate by temporal clocking of an electronic switching unit, via which each phase of the alternating voltage gate can be connected either to a positive pole or to a negative pole of the direct voltage gate. The positive pole and/or the negative pole of the direct voltage gate is connected via at least one capacitor to a ground connection. The ground connection can be connected to an external ground, and the connection between the capacitor and the ground connection is guided via at least one switch element. The arrangement also relates to a motor vehicle having the electric powertrain. A diagnosis arrangement includes a voltage source and monitors the state and function of a switching element.

Shock protection for radio-interference-suppressed voltage transformers in a potential-free DC voltage network

A method for regulating the current through an electromagnetic actuator. The actuator, a first switch and a current-measuring circuit form a series circuit. A free-wheeling diode is parallel-connected to the actuator. The first switch is closed and opened by a control and a pulse generator using a PWM signal (PWM=pulse width modulation) in such a way that the current flowing through the actuator and measured by the current-measuring circuit is regulated to a setpoint value (SW). The time duration of one on and off switching cycle of the PWM signal is altered, and a so-called dither function in the form of a low-frequency oscillation is superimposed on the PWM signal.

Controller, in particular motor vehicle controller

The invention is directed to a method for balancing a current controller for controlling a current. The current controller is configured to adjust the current to a desired value of current while considering an actual value of the current determined by a measurement. The current controller is balanced while considering the deviation between the real magnitude of the current and the actual value applied to adjust the current.
