Design of Induction Heating Power Based on the Power Adjusting Technique and the Frequency Tracing

Abstract:

The ultrahigh frequency (more than 1MHz) of the HF Induction Heater need to be reached for surface-heat-processing of tiny mental components, which is not available by the traditional HF Induction Heater. To satisfy these requirements, by using the high-speed field effective transistor (FET) and high-speed phase locked loops (PLL: MM74HC4046), the frequency of inverts for induction heater and the power can arrive at more than 1MHz and 5.5kW respectively at the same time. Additionally, it achieves the power adjusting technique and the frequency tracing. The experimental shows that this design can both achieve the high frequency and efficiency, and meet the requirement of the surface-heating-process of the tiny components.
