Title:
POWER SUPPLY CONTROL CIRCUIT AND METHOD, STORAGE MEDIUM, ION GENERATOR AND PURIFIER
Document Type and Number:
WIPO Patent Application WO/2021/189892
Kind Code:
A1
Abstract:
A power supply control circuit, method and apparatus, a storage medium, an ion generator and a purifier. The power supply control circuit comprises: a high-voltage generation circuit (10), a current sampling circuit (20) and a high-voltage controller (30). The high-voltage generation circuit (10) is configured to provide power supply voltage for an electrostatic dust removing apparatus of the ion generator; the current sampling circuit (20) is configured to sample the working current of the ion generator and feed a current sampling signal to the high-voltage controller (30); and the high-voltage controller (30) is respectively connected to the high-voltage generation circuit (10) and the current sampling circuit (20) and is configured to control the high-voltage generation circuit (10) according to the received current sampling signal so as to adjust the output voltage of the high-voltage generation circuit (10). In this way, effective power supply control can be performed on the ion generator, realizing anti-static interference, guaranteeing the ionization intensity of the ion generator and improving the purification effect of an ionic purifier.
