Abstract
A dryer includes: a chamber; a first electrode disposed on a first side of the chamber; a second electrode disposed on a second side of the chamber, the second side facing the first side; a radio frequency (RF) power supply configured to operate using an alternating current (AC) voltage input from an AC power source and apply an RF signal to the first electrode and the second electrode; an impedance matching circuit configured to perform impedance matching between the RF power supply and the first electrode and the second electrode; and a frequency control circuit configured to adjust a frequency of a switching signal for turning the RF power supply on or off based on a change in a magnitude of the AC voltage.

A dryer, comprising:
- a chamber;
- a first electrode disposed on a first side of the chamber;
- a second electrode disposed on a second side of the chamber, the second side facing the first side;
- a radio frequency (RF) power supply configured to operate using an alternating current (AC) voltage received from an AC power source and apply an RF signal to the first electrode and the second electrode;
- an impedance matching circuit configured to perform impedance matching between the RF power supply and the first electrode and the second electrode;
- and
- a frequency control circuit configured to adjust a frequency of a switching signal to turn the RF power supply on or off based on a change in a magnitude of the AC voltage.
A method for controlling a dryer comprising a radio frequency (RF) power supply configured to operate using an alternating current (AC) voltage input from an AC power source and apply an RF signal to a first electrode and a second electrode, and an impedance matching circuit configured to perform impedance matching between the RF power supply and the first electrode and the second electrode, the method comprising:
- identifying, by a frequency control circuit, a change in a magnitude of the AC voltage;
- and
- adjusting, by the frequency control circuit, a frequency of a switching signal for turning the RF power supply on or off based on the change in the magnitude of the AC voltage.
