Power Quality Enhancement Using Custom Power De... May 2026

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. Classification of Custom Power Devices

The UPQC is considered the most powerful CPD as it combines both converters via a common DC link. power quality enhancement using custom power de...

Power factor correction, load balancing, and mitigating current-related harmonics. 3. Unified Power Quality Conditioner (UPQC) are a new generation of power electronic controllers

Static Transfer Switch (STS), Static Current Limiter (SCL), Static Circuit Breaker Fast switching for fault isolation and rapid load transfer. It injects a synchronized voltage into the distribution

It injects a synchronized voltage into the distribution feeder to maintain a constant load voltage during source disturbances.
