The ever increasing demand of electricity has laid enormous pressure on the existing power generation infrastructure. Besides power generation, transmission loss is also one of the main worries as huge transmission losses are being incurred by the present AC transmission. Hence, HVDC transmission has become an interesting preposition across the globe due to its low transmission losses, asynchronous interconnection, and the capability to deliver bulk power for long distance transmissions. HVDC capacitors, thus, find major applications in industrial, commercial, and energy and power sectors.
