High-voltage module

High voltage modules by Liebherr are converting an input voltage of 1 x 1000VAC at 16-50Hz to an insulated and stabilized output voltage of 680VDC. The output power of 50kW enables the supply of HVAC and other high power equipment in typical railway coaches. The compact assembly draw-out unit with high packing density is realized with fluid cooling and newest technology of semiconductors with lowest switching losses, power capacitors and inductive components. For bypassing short input voltage interruption, an energy buffer with a power capability of 50kW over 30ms is implemented.
