Abstract
Official abstract text for this publication.
A DC to DC converter assembly, for connecting first and second high voltage DC power transmission networks, comprising first and second modular multilevel converters, each converter including a first converter limb having first and second limb portions, each limb portion including a least one module switchable to selectively provide a voltage source and thereby vary the magnitude ratio of a DC voltage (V1, V2) across the first and second terminals of a respective converter and an AC voltage (VAC) at the third terminal of the corresponding converter, the DC to DC converter assembly further including a first link electrically connecting the third terminal of one converter, with the third terminal of the other converter, and at least one converter further including a controller configured to switch the first and second limb portions in the first converter limb of the said converter into simultaneous conduction to divert a portion (IDiV1) of current flowing within the said converter away from the first link.
First claim
Opening claim text (preview).
The invention claimed is: 1. A DC to DC converter assembly for connecting first and second high voltage DC power transmission networks, comprising: first and second modular multilevel converters each modular multilevel converter including: first and second terminals connectable in use to a respective one of the first and second high voltage DC power transmission networks; a first converter limb extending between the first and second terminals of the modular multilevel converter…
