The present invention relates to an integrated transformer configuration having a first coil formed from an electrically conductive material having a spiral course with an essentially rectangular cross section. The transformer has a second coil with a spiral course. The first and the second coils are arranged such that they are electrically insulated from one another. The ratio between the height and the width of the rectangular cross section of the first coil is greater than 1.
摘要:
A power switching device has a power switching transistor connected in series in a load circuit with an inductive load portion and a commutation circuit. The commutation circuit is connected in parallel with the gate-drain or base-collector path of the power transistor and has a first Zener diode, which determines the commutation clamping voltage for switching on the power switching transistor during commutation, and an oppositely biased normal diode that is connected in series with the first Zener diode. The commutation circuit further has control elements in order to reduce, during a short time, the commutation clamping voltage at the beginning of each commutation cycle or after an adjustable delay from the beginning of each commutation cycle.
