Abstract
A driving circuit for supplying a radio frequency electrical signal to the applicator section of a radio frequency dryer includes a voltage controlled oscillator, supplying a signal to an amplifier circuit. The amplifier circuit supplies an amplified signal to the applicator section of the dryer via an impedance match circuit. The signal supplied to the applicator section is compared in phase with the output of the voltage controlled oscillator and phase deviations are utilized to produce a signal which controls the frequency of the voltage controlled oscillator output, such that the applicator section of the dryer is driven at its resonant frequency.
