ABSTRACT:
A power loop has a power-loop emitter and a power-loop receptor located in different housings and connected via a power-loop conductor that is at least partially exterior to both housings. By means of a current transformer inductively coupling the conductor to the emitter or receptor, the power-loop also provides for electrical insulation between the emitter and the receptor. The emitter and receptor being distant from each other offers greater flexibility in the positioning and design of the galvanic separation between the emitter and the receptor or the supplied gate-drive, respectively. For example, the local voltages of converter levels ranging up to the supply voltage of e.g. 21 kV RMS of the multilevel converter can thus be insulated from the global earth potential of the power-loop emitter. Several power-loop receptors can be coupled to the same power-loop conductor to be fed by the same power-loop emitter.
