Induction cooking

Quicker, more consistent heating and better energy-efficiency have made induction cooking a growing consumer trend. But designing an induction cooking system is not without its challenges. Designers often face the problem of high field failure rates caused by grid disturbances, and the replacement and service costs for stoves are very high. On the other hand, the competitive nature of the market increases cost pressure and limits use of protective features.

At the same time, as the market evolves towards connectivity, new security issues arise for induction cooking technology. Also, there is immense component stress since the applications requires high power. The net effect of all this: powerful semiconductors are subject to high electrical and thermal stress.

Optimizing induction cooking technology

At Infineon, we are well equipped to help you overcome all the challenges common to induction cooking appliances.  
In our full-spectrum portfolio you can find cost optimized solutions engineered for high reliability and high immunity against negative voltage undershoots, such as the RC-H5 IGBT, the 2EDL and 2ED compact gate driver, and the XMC MCU family.
Our products also operate under high EMC disturbances and surge conditions, and enable high power operation with a high system-efficiency due to low VCEsat, VF, Eoff and Rth. You can ensure secured identification of the cooking unit with the home automation network by integrating our OPTIGA™ Trust products. Choose products and expertise from Infineon and easily design your induction cooking applications to fulfill the latest market demands.
