At the beginning, there were only small DC networks within narrow local boundaries, which were able to cover the direct needs of industrial plants. The growing trends towards the rapid increase of load and present development systems have made it necessary to transmit more power over long distances to cope with the demands. The reliability and flexibility of power transmission by AC isindisputable. The problem of AC transmission particularly in long distance transmission has lead to development of DC transmission. It has been proved that AC is better from generation and utilization point of view while DC is preferable for transmission over very long distances. In a combined AC and DC system generated AC voltage is converted into DC voltage at sending end and DC voltage is inverted into AC voltage at the receiving end for distribution purpose.
