Interference in system voltage causing short-term voltage drops (ranging from several to dozens of cycles) on the load side is a primary cause of failures in sensitive loads and computer equipment. The Dynamic Voltage Restorer (DVR), utilizing advanced PWM interlaced technology, can rapidly regulate voltage during sudden system voltage fluctuations. It simultaneously eliminates three-phase imbalance and flicker, while maintaining output voltage stability through precise regulation of voltage deviations, thereby achieving effective load protection.
