The UPQC is considered the most powerful CPD as it combines both converters via a common DC link.
are a new generation of power electronic controllers designed for medium to low voltage levels (typically 1 KV through 32 KV) to ensure high-quality power delivery. Unlike Flexible AC Transmission Systems (FACTS) which focus on high-voltage transmission, CPDs are specifically applied at the distribution level to protect sensitive consumer equipment.
