AI Technical Summary

Technical Problem

Existing power transmission voltage regulators have slow response speed and low voltage regulation accuracy, and cannot adapt to load fluctuations, resulting in voltage fluctuations that affect the stability and safety of power systems and electrical equipment.

Method used

The system employs a dual-channel comparison module to detect input and output voltage deviations, and uses a graded compensation module to adaptively activate the compensation unit. Combined with signal conditioning and high-precision reference voltage generation, it achieves fast response and high-precision voltage control, and integrates overvoltage and overcurrent protection functions.

Benefits of technology

This reduces the voltage response time to within 10ms and controls the output voltage error to within ±1%, improving the equipment's ability to cope with sudden load changes and its operational safety.
