A current source element (10) for a current source converter comprises first and second voltage terminals (V1, V2). The current source element (10) also comprises a chain of modules (M1, M2, M3....MN) and an inductor (L) connected in series between the voltage terminals (V1, V2). Each module (M1, M2, M3....MN) includes at least one pair of semiconductor switches (12, 14) connected in parallel with a capacitor (20). The semiconductor switches (12, 14) are controllable in use to provide a continuously variable voltage source to directly control the rate of change of current in the inductor (L). |
