In traditional kitchen cooking, heating a pot of water often relies on open flames or electric heating plates, which transfer heat indirectly through the cookware. This method not results in significant energy loss but also lower heating efficiency. Today, with the advancement of induction heating technology, kitchen heating methods have undergone a breakthrough—allowing the cookware itself to become the heat source.

Induction heating technology operates based on the principle of electromagnetic induction. The system drives a copper coil at high frequency through a resonant circuit, generating an alternating magnetic field. When a magnetic cookware is placed within this field, eddy currents form at its bottom. Combined with the skin effect and hysteresis loss, electrical energy is rapidly converted into thermal energy, enabling efficient and precise heating control. It is worth noting that the larger the current in the induction coil, the stronger the eddy currents in the cookware, and the faster the heating speed. Meanwhile, higher frequencies concentrate the eddy currents closer to the bottom surface, reducing the effective conductive cross-sectional area and indirectly increasing resistance and thermal efficiency.
However, achieving efficient induction heating relies heavily on a key power switching device—the IGBT (Insulated Gate Bipolar Transistor). It must simultaneously handle high currents and achieve high-speed switching, and its reliability directly affects the performance and lifespan of the entire unit. Incidents of IGBT failure in some induction hobs are often due to instantaneous current or voltage exceeding the device’s tolerance, leading to overheating and damage.
As a professional built-in induction cooker manufacturer, Katro Appliances understands the critical impact of IGBT quality on product stability. Therefore, its built-in induction hobs fully adopt Infineon’s high-performance IGBT modules, significantly reducing the incidence of failures and enhancing overall durability and energy efficiency.
