Reverse conducting IGBTs for resonant applications

Like all the RC-H5 products, the discrete 650V power semiconductor also distinguishes itself in greater energy efficiency than the earlier generations. The switching losses have been reduced by a further 30%. This allows designers to work with switching frequencies of up to 40kHz. Altogether the discrete power semiconductor is characterised by better energy efficiency leading to a 5% saving in energy consumption of the whole system.

Alongside their outstanding energy efficiency, systems operating on the basis of the RC-H5 650V also have significantly improved reliability due to the increased blocking voltage which gives more design margin. The ability of the 650V component to provide soft or hard switching as required not only means greater flexibility of use but also that less strain is put on the system as a whole. The improved EMI behaviour of the component is also a significant benefit in fast and soft switching systems where less filtering is then required. In addition, optimised thermal performance enables trouble-free operation in ambient temperatures of up to 175°C.

Roland Stele, Marketing Director, IGBT Power Discretes, Infineon Technologies, comments: “Induction cooking holds enormous potential for energy saving in household appliances and for environmental benefits. With the new discrete RC-H5 650V Infineon is extending the range of products for household appliances enabling our customers to develop highly reliable systems which require fewer resources.”

The RC-H5 is available in the current classes 20, 40 and 50A. Sample models will be supplied in June 2014, and in the same month serial production will start.
