Embodiment Construction

[0046] FIG. 1 shows a device 2 for powering an electric dipole 4 . In this case, the dipole 4 is connected to the device 2 by means of a filter 6 equipped with an input 8 .

[0047] Dipole 4 is, for example, a resistor.

[0048] Filter 6 is, for example, a filter including only filter capacitor 12 connected in parallel to each end of dipole 4 . In this case, device 2 makes it possible to avoid the use of filter inductors.

[0049] The device 2 comprises a polyphase voltage source 16 and a magnetic coupler 18 for connecting the voltage source 16 to the dipole 4 .

[0050] The power source 16 is an N-phase power source, where N is an integer greater than or equal to 4. The power supply 16 thus provides N voltages Vi, where the value i is the number of phases between 0 and N-1. By convention, the angular offset between voltages V0 and Vi is equal to 2πi / N. Thus at voltage V0 to V N-1 The angular offsets between are regularly distributed between 0 and 2π radians, as shown in...

Abstract

The invention relates to a method for supply to a magnetic coupler comprising several pairs of windings, each pair being formed from a first and a second adjacent paired winding, magnetically coupled to each other by means of a core of magnetic material. The method further consists of supplying the first winding of each pair with a supply voltage or current out of phase by an angle a with relation to the supply voltage or current for the second winding of the same pair. The absolute value of the angle a is greater than or equal to 4p / N for at least one pair of windings.

Description

technical field [0001] The present invention relates to a method and apparatus for providing a magnetic coupler. Background technique [0002] Magnetic couplers (polyphase-to-phase transformers) are used, for example, to connect loads to a multiphase power supply. [0003] It is known to use a multi-phase power supply that can generate N cycles of supply current or voltage angularly offset from each other, where N is an integer greater than or equal to 4. The angular offset between the applied supply currents or voltages is evenly distributed between 0 and 2π radians. An angular shift of 2π radians corresponds to a period of the current or voltage. [0004] Known magnetic couplers comprise several pairs of windings, each pair consisting of a first and a second adjacent winding, which are magnetically connected to each other by means of a core or core made of magnetic material. Different structures of known magnetic couplers are described in the following articles: [000...
