For tapping power from an HVDC line (L), a self-commuted current-source converter (SR1) is connected into the line and adapted to generate a high-frequency alternating voltage (UC). This voltage is stepped up in a first transformer (T1) and is transferred via potential-separating capacitors (C1, C2) to a second, step-down transformer (T2) at ground potential. The latter transformer is connected to a local network (LN) via a rectifier (SR2), an intermediate link (C3) and an inverter (SR3). |
