Electrostatic precipitator and control method thereof

An electrostatic precipitator comprising:

• a dust collecting sheet configured to emit ions and configured to collect an aerosol charged by the ions from air flowing along an air flow path through the electrostatic precipitator;
• a power supplier electrically connectable to the dust collecting sheet;
• a plate-shaped structure arranged upstream of the dust collecting sheet along the air flow path, the plate-shaped structure comprising at least one of a filter mesh or a grille comprising a plurality of openings;
• a potential stabilizer, arranged between the plate-shaped structure and a ground, to stabilize a potential of the plate-shaped structure, the potential stabilizer including a relay configured to connect to and disconnect from the plate-shaped structure and the ground;
• and
• a controller configured to control the relay to be repeatedly turned on and off at predetermined time intervals so that the plate-shaped structure and the ground are repeatedly connected and disconnected at the predetermined time intervals based on the power supplier supplying power to the dust collecting sheet.
