This type of stabilizer is more versatile and is the most commonly used type, for use with three phase / single phase machines / loads. The basically consists of 3 single phase units of 1/3 capacity each, connected in ‘STAR’. In this type, the output voltage on all three phases are balanced even if the input voltage and the loads connected on the three phases are entirely different (unbalanced). This uses three motors along with three variacs and three solid state control circuits.
