Abstract:
Nowadays increasing the efficiency/power density and keeping the cost low are key points in all power electronics applications, especially in the consumer area. One of the most critical applications here is induction heating. In order to further increase the power density in induction cooking applications, different strategies have been investigated, but surely the most promising one is to heighten the switching frequency. This leads to savings in weight, space and cost, but also sets the demand for better switching devices. Until now the market did not offer a well performing device at a reasonable price. Technologies like SiC MOSFETs or SIC JFETs have been explored, but at the end were too expensive. Now, the new Field Stop II (FS2) IGBT technology is the most promising candidate to enable designs with higher switching frequencies. This paper presents the potentialities of the FS2 family and shows performance evaluation in a certain application.
