Control System Design of High-Power Induction Cooker

This artical designed and produced a half-bridge series resonant induction heating cooker induction cooker whose power is15kHz . The main controller of the cooker is S3F9454, and SG3525 is for adjusting the frequency, the principle of induction heating is the basis of its , by the load current feedback loop and PI we can get the adjustment of the frequency and power of the system. The practical use shows that the output power of the system is stable, and it has the advantages of high thermal efficiency and fast heating.
