22.1 Introduction

High-voltage direct current (HVDC) energy transmission was developed in the late 1920s, and the first commercial HVDC submarine cable started operation in 1954. This system used mercury-arc valves, which required constant maintenance and rebuilding. With the development of the high-voltage and high-power thyristors in the early ...
