1. A liquid cooling static synchronous series compensator (SSSC) system, comprising:
one or more series connected inverter valve modules operable to inject reactive power into a power transmission line of a high-voltage power transmission system, each inverter valve module including a plurality of inverter valve units attached to a liquid cooling block (LCB) having an enclosed fluid chamber; and
the liquid cooling block having an aperture to expose a portion of each of the plurality of inverter valve units for direct impingement of liquid coolant in the enclosed fluid chamber, wherein adjacent inverter valve units of the plurality of inverter valve units are spaced apart with first insulating materials such that the liquid cooling block has voltage isolation relative to other liquid cooling blocks of the SSSC system.
