Abstract
A device for connection to an impedance having a mainly inductive character. The device comprises a reactive element. Furthermore, the device is provided with inputs for inputting output signals of electric inverters for parallel supply and at least one output for connection to a supply terminal for a phase of the impedance, such that the device is composed to substantially filter out a high-frequency differential component of at least two output signals during use.

A device for connection to an impedance having a mainly inductive character, comprising:
- a reactive element;
- inputs for inputting output signals of multiple electric inverters for parallel supply;
- and
- at least one output for connection to a supply terminal for a phase of the impedance, such that the device is configured to substantially filter out a high-frequency differential component of at least two output signals during use.
