Drop in replacement IGBT reduces cost of induction heating

New Products |
By Nick Flaherty

Induction cooking appliances commonly make use of resonant topologies which allow bi-directional current flow and need a discrete IGBT that performs best at switching frequencies from 18 to 40 kHz with low losses.

The new RC-E family features an IGBT with monolithically integrated reverse conduction diode for resonant switching that is also optimized for low switching and conduction losses. Lower losses allow designers to achieve efficiency and power targets for induction cooking applications more easily so that less energy is consumed for cooking, leading to energy costs for consumers. With low Eoff, VF, Rth and Vce(sat), the device architecture sets a new industry benchmark in price/performance and ease-of-use.

The INFIPC201610-004 fulfills all the requirements for soft switching applications and efficiency as well as EMI standards with a lower BoM cost. The RC-E is offered in a standard TO-247 package allowing a drop-in replacement for existing designs.

Samples are available now and the devices are in production. The family will be launched with two devices: 15 A and 25 A, both with the most commonly used blocking voltage of 1200 V.
