Research On High Frequency Induction Heating Control System Based On FPGA

In recent years, the technique of FPGA is focused on and applied in numerical control system widely because of its superiority. The techniques of FPGA and wireless communication on high frequency induction heating control system are discussed in order to build a safe and steady high frequency induction heating environment in this dissertation.Firstly, the concepts and the techniques in which the high frequency induction heating control system involved are introduced. Then the principle and feasibility of system are deep studied. The topological structure of main circuit is series resonance and the regulation of power is capacitive phase shift. The parameters and symbols of components in system are determined. Finally, the circuits are designed according to the design flow of FPGA.The technique of wireless communication is brought into the high frequency induction heating control system. The system is much smaller and steadier in that the circuit of RF wireless communication and other control circuits are integrated into an FPGA chip by the technique of FPGA. Therefore, the control of High Frequency Induction Heating Control System will be more intelligent and more safety to operate.The induction heating control system that is studied in this dissertation runs well. It is feasible to realize the digital intelligent control system with the technique of FPGA and wireless communication.
