  • Multi-level cascaded H-bridge STATCOM circulating cooling fluid within enclosure
    Patent number: 10193340
    Abstract: A static synchronous compensator configured to be installed in and provide reactive power to a medium voltage electric distribution system. There is a multi-level cascaded H-bridge (CHB) converter in an enclosure, having a nominal operating voltage in the medium voltage range. There is a first electrical bushing connecting the medium voltage electric distribution system to the input of the CHB converter. There is a second electrical bushing connecting ground or floating ground to the output of the CHB converter. There is a cooling system, which circulates the cooling fluid between in the interior of the enclosure to cool the CHB converter. There is a controller to control the converter to output reactive power at a medium voltage level.
