An electrical assembly (20) comprises: a voltage source converter (22) including first and second DC terminals (26,28) and at least one AC terminal, the first and second DC terminals (26,28) being respectively connectable to first and second DC power transmission media (38,40) connected to a DC electrical network (41), the or each AC terminal being connectable to an AC electrical network (46); a DC tap (24) including first and second tap terminals (52,54), the first and second tap terminals (52,54) being respectively connectable to the first and second DC power transmission media (38,40), the DC tap (24) including a tap limb (48) extending between the first and second tap terminals (52,54), the tap limb (48) having first and second tap limb portions (48a,48b) separated by a third tap terminal (56), each tap limb portion (48a,48b) including a respective DC blocking capacitor, the third tap terminal (56) being connectable to an electrical load (64); a current return path (58) configured to electrically interconnect the or each AC terminal to the third tap terminal (56); a converter unit (22); and a controller (100) configured to selectively control the converter unit (22) to generate at least one first non-fundamental frequency alternating current component (70a,70b,70c) at the or each AC terminal to drive a non-fundamental frequency alternating current (72) to flow through the current return path (58) and in the third tap terminal (56), and to selectively control the voltage source converter (22) to modify the or each first non-fundamental frequency alternating current component (70a,70b,70c) at the or each AC terminal so as to form a first current (74a) flowing between the first DC terminal (26) and the first tap terminal (52) and to form a second current (74b) flowing between the second DC terminal (28) and the second tap terminal (54), each of the first and second currents (74a,74b) including a direct current component and at least one second non-fundamental frequency alternating current component, so as to enable the DC tap (24) to draw power from the DC electrical network (41) for supply to the electrical load (64).
