Why Do Static Voltage Stabilizers Have High Accuracy?

The high precision of the static automatic voltage regulator is reflected in its use of pulse width modulation (PWM) and power electronic devices (such as IGBTs) to compensate for input voltage changes in real time. Moreover, the control system is usually equipped with a digital signal processor (DSP) for high-speed sampling and closed-loop feedback. This electronic control method achieves extremely short settling time (typically 20 to 30 milliseconds) and can finely correct for tiny voltage deviations.
