Abstract
Voltage sag is one of the main concerns of industries today. These voltage sags could cause high negative impact on productivity, which is certainly an undesirable aspect in industrial and commercial applications. Current tap changing transformers used in distribution systems have proven to be inadequate in solving these problems related to line regulation. A solution to these problems is to install an AC voltage-voltage converter that has been developed primarily for voltage sag correction. This system incorporates fast Insulated-Gate Bipolar Transistor (IGBT) switching technology, Pulse-Width-Modulation (PWM) controls and closed-loop feedback designed to provide the speed and efficiency required by industrial customers. Furthermore, the system will provide the flexibility of installation with or without the incorporation of tap changing transformers.
