Zusammenfassung:	A converter, for use in high voltage direct and alternating current power transmission comprises a primary charge transfer converter. The charge transfer converter includes first and second primary terminals for connection to one or more electrical networks. The primary charge transfer converter also includes a plurality of charge transfer elements and a plurality of primary switching elements which are connected in a cascade circuit between the first and second primary terminals. Each charge transfer element includes at least one resonant circuit. The primary switching elements are operable to selectively cause charging and discharging of each resonant circuit to transfer charge between the charge transfer elements and thereby create a voltage difference between the first and second primary terminals.
