VOLTAGE SOURCE CONVERTER AND METHOD OF CONTROLLING A VOLTAGE SOURCE CONVERTER

摘要

A VSC converter for conversion between dc and ac voltage comprises at least two serially connected phase legs (101-103). The outputs of the conversion stages form phase outputs (131-133) to be connected to a phase of an alternating voltage network via a respective transformer (121a-123a). The configuration of the conversion stages reduces the requirements on the individual components of the VSC converter.
