Abstract
Improved apparatus for discharging power from a high-voltage direct current line. A direct voltage convertor is connected in series with a smoothing filter and a DC high voltage line on one side and a second smoothing filter and a power discharge inverter on the other side. The rated voltage of the discharge inverter is substantially lower than the line voltage and the direct voltage convertor applies the lower voltage to the discharge inverter.
