Design and Implementation of A Resonant Converter with Passive Snubber for Induction Heating |
| |
| Abstract: | Induction heating is a new type of industrial heating. This paper presents a resonant converter with passive snubber for induction heating. Firstly we use Matlab/Simulink to build a simulation model, and then realize the function of automatic frequency tracking based on CD4046 PLL, finally we design a 3 kW ultra-audio-frequency induction heating prototype, which is controlled by a PIC microcontroller. The results of the experiment show that： the induction heating resonant inverter can work stably, reliably, with a high heating efficiency. |
