CONVERTER CONTROL

摘要

A multilevel voltage source converter (11) for high voltage DC power transmission and reactive power compensation comprises at least one module (40) including at least one switch (12) and an electronic bypass system. The electronic bypass system is controllable to activate the at least one switch (12) in the module (40) to cause a short circuit through the activated switch (12) and thereby maintain a converter current (36) through the module (40) and the multilevel voltage source converter (11).
