The Contradiction Between Ac Power Voltage Regulation Technology And High-precision Output

The basic working principle of the industrial power conditioner relies on changing the conduction angle or series impedance of internal components (such as silicon controlled rectifiers) to change the output voltage. Because the output depends on the real-time waveform of the input power grid, and the regulating device itself has a limited response speed to voltage and load changes, the output voltage is usually accompanied by harmonic distortion and transient fluctuations.

electrical power conditioner often introduces high-order harmonics and nonlinear distortion during voltage regulation. This waveform distortion has a substantial impact on the power supply quality of precision equipment, leading to measurement errors, control deviations, and even abnormal equipment functions. In laboratories, communication base stations, and sensitive electronic systems requiring high-stability, low-noise power supplies, this waveform distortion is difficult to tolerate. Unlike regulated power supplies that can obtain stable DC output through a precision reference source and closed-loop feedback, the single phase power conditioner lacks sufficient feedback compensation mechanism to cope with minor voltage deviations.
