History of High Voltage Direct Current Transmission (HVDC)· PDF fileThe heart of a HVDC Transmission System is truly the electronic power converter valves. These valves are built around the thyristor device and they convert AC into DC at the Rectifier station and DC into AC at the Inverter station. Originally, the thyristors were triggered with an electrical current pulse,

Transformer - Wikipedia transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits.A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core. . Electrical energy can be transferred between ...
