Title:
HIGH-VOLTAGE ELECTROSTATIC PRECIPITATOR SYSTEM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/007057
Kind Code:
A1
Abstract:
Disclosed is a high-voltage electrostatic precipitator system, used for an electronic device (500) having a pyroelectric infrared sensor. The pyroelectric infrared sensor comprises a filter (5). The high-voltage electrostatic precipitator system comprises a DC power supply module (100), a self-oscillating circuit (200), a transformer (T1), and a voltage N-multiplication rectifier circuit (400). The self-oscillating circuit (200) converts a DC voltage output by the DC power supply module to a first AC voltage, and applies the first AC voltage between two ends of a primary winding (N2), and a second AC voltage generated between a first end and a second end of a secondary winding (N3) is applied to between a first input end and a second input end of the voltage N-multiplication rectifier circuit (400). The voltage N-multiplication rectifier circuit (400) converts the second AC voltage to a high DC voltage, so as to form a high voltage electrostatic field between the first output end and the second output end of the voltage N-multiplication rectifier circuit. The filter is in the high voltage electrostatic field and can remove dust thereat.
