Enhancement of electric field uniformity using 3-phase circular electrodes in RF heating applications.

ABSTRACT: This paper introduces a novel electrode structure designed to enhance electric field uniformity in radio frequency heating applications, such as food processing. The proposed 3-phase circular electrode structure, the top electrode, consists of innermost, middle, and outermost electrodes, with each electrode supplied with a voltage of a different phase. By utilizing relative phase differences between the top electrodes, the electric field distribution between the top and bottom electrodes can be effectively modified to apply a uniform electric field on the food sample. A 3D computational simulation model was used to analyze the electric field uniformity at an operating frequency of 13.56 MHz and compared it with conventional single-phase rectangular electrodes. Both simulations and experime
