Full Bridge Induction Heater Schematic. The main blocks are an emi filter plus some over voltage and over current protections a rectifier bridge plus the bus capacitor. Induction cooking functions based on the principle of the series l c resonant circuit where the inductance l is the cooking element itself.
Induction heating cooker is based on high frequency induction heating electrical and electronic technologies. Induction heating for melting hardening and heating. Many layers of copper are used to allow them to carry over 50a of current.
Commercially they are used for heat treating brazing soldering etc as well as to melt and forge iron steel and aluminum.
The following image shows the double coiled air cored isolation transformer design. Introductioninduction heaters are used to heat conductive materials in a non contact process. Figure 2 shows a block diagram of an induction cooker inverter. The entire induction heating system is shown in the block diagram of fig.
