ABSTRACT
The performance improved of electric field distribution and intensity for dielectric heating has been presented in the paper and the results are discussed. It is a technique challenge in dielectric heating is to control the electric field distribution by increasing input power ports on the capacitor copper plates. The simulation of analysis was divided the input power port into 4 cases, which are one port, two ports, four ports and six ports, respectively. By each case, can be used the input power port at different positions on the plate for provide to the position and number are the most appropriate. The distribution and intensity of electric field on the dielectric load will be analyzed by using the CST EM STUDIO program. We show that the electric field intensity can be distributed over all the entire copper plate by increasing input power ports and the positioning to suitable. In the simulation results, we used the electrical power and resonance frequency are 600 W and 39 MHz, respectively. Results have shown that the distribution and intensity of electric field on the dielectric load will be occurred at the near point of input power ports are the most and decreased when the distance away from the power input port. However, in this paper the input power port of four ports case is an equilibrium position, the electric field intensity is appropriated distribution. Which can be the distribution of electric field is 74% of area comprehensive at intensity of electric field is 26.1 V/m. These results demonstrate that it is possible to achieve higher electric field distribution and intensity for dielectric heating where increases input power ports on the copper plates are used.
