摘要:
The invention relates to a circuit arrangement comprising at lest two electrical components (1, 2) and an energy accumulator (Cd) which are arranged on electroconductive plates (3, 5 and 6) in such a way that current paths which are as short as possible and have a minimal parasitic inductance are created. The inventive circuit arrangement is preferably suitable for a voltage transformer.

A control device for a three-phase machine contains an inverter, which can be connected on the input side to a direct voltage source and on the output side to the three-phase machine. The control device further has a reactive power converter, which on the output side is terminated by a capacitor and on the input side is disposed electrically parallel to the inverter, namely on the input side of the inverter.
摘要:
A regulating apparatus for a three-phase AC machine has a DC controller and an inverter. An input of the inverter is coupled to the DC controller and an output of the inverter can be coupled to the AC machine.
摘要:
A voltage source is formed by a series connection of a first energy accumulator (accumulator B1) and a second energy accumulator (capacitor C1). The voltage (UC1) of the second energy accumulator (C1) is adjusted in such a way that the sum of the voltages via the first energy accumulator (UB1) and the second energy accumulator (UC1) are the same as that of a pre-determined desired voltage (UVsoll).
