o Power re-conversion on earth (PV, solar thermal) o High efficient long distance power transmission on ground (HVDC) The beaming or wireless transmission of power relies either on microwave or laser technology. In this study both ways has been treated, but major emphasis is put on laser systems. Two basic concepts exist:
This article reviews the actual status and the advantages and disadvantage of AC and DC transmission systems. UHVDC links are actually the most effective solution to transfer bulk power over distances of 1000 km or more. Submarine cables for HVDC applications are only available up to 500 kV. Self-commutated voltage source converters (VSCs) (especially IGBTs)
