DEIF’s Digital voltage controllers are Digital Automatic Voltage Regulators (AVR) that are essential components designed for alternators with SHUNT, AREP, or PMG excitation. This device plays a crucial role in monitoring and regulating the alternator’s output voltage to ensure stable and reliable performance.

Excitation Methods:

SHUNT Excitation: SHUNT excitation involves using the alternator’s output to power the AVR. This method is commonly used in smaller alternators and provides a simple and cost-effective solution for voltage regulation.

AREP Excitation: AREP (Auxiliary Winding Regulation Excitation Principle) utilizes auxiliary windings in the alternator to supply power to the AVR. This method enhances the alternator’s ability to handle transient loads and provides better voltage stability.

PMG Excitation: PMG (Permanent Magnet Generator) excitation uses a separate permanent magnet generator to supply power to the AVR. This method offers superior voltage regulation and is ideal for applications requiring high reliability and performance.
