There is provided a current control circuit (20) for connection between a first electrical network (42) and a converter, the current control circuit (20) comprising:



first and second input terminals (24,26) for connection to the first electrical network (42);
first and second output terminals (28,30) for respective connection to converter terminals (46,48) of the converter;
first and second switching limbs, the first switching limb interconnecting the first input and output terminals (24,28), the second switching limb interconnecting the second input and output terminals (26,30), each switching limb including a respective switching element (32,34,36,38);
a director limb (76) extending between the first and second output terminals (28,30), the director limb (76) including at least one current director element (84) and at least one first resistive element (86), the director limb (76) including an intermediate terminal (82);
a second resistive element (88), a first end of the second resistive element (88) operably connected to the intermediate terminal (82), a second end of the second resistive element (88) operably connectable to ground; and
a controller (96) programmed to selectively control switching of each switching element (32,34,36,38) so as to, in use, regulate a flow of current from the first electrical network (42) to the converter.
