Research on Frequency Tracking Technology of High Frequency Induction Equipment

With the development of luxury cruise ships and large offshore platforms, the use of high-frequency electromagnetic heating power sources to replace fireworks for thin steel plate leveling is a new development trend in the shipping and offshore industries. The technical difficulty of high-frequency induction power supplies is frequency track. The frequency tracking circuit in this article uses CD4046 as the core, which not only realizes frequency tracking but also realizes the dead time setting, ensures that the power supply can realize frequency scanning and maximum frequency tracking, and ensures that the circuit always works in resonance or quasi-resonance state, The output is more efficient at this time.
