MEDI’s latest design in the field of Static Voltage Stabilizer released in 2020 is TrioStat. 

The design can only be used for three phase application. Three phase PWM is done by using only three IGBT modules or six discrete IGBTs. The topology is patented by MEDI.

The technology is up to 90KVA using discrete IGBT and up to 200KVA using IGBT module.
