The modular HVDC test system is comprised of switchgear, voltage regulator, controlled silicon, voltage-multiply circuit (including isolation transformer, charging transformer, HV silicon stack and capacitors), resistive voltage divider, control and measurement system.
The cylinder stacked type HVDC module is newly developed. The DC high voltage generator and resistive voltage divider is integrated in the same cylinder tube. This stacked design allows the more modules to connect in series.
