STMicroelectronics has released a new class of IGBTs with an increased breakdown-voltage capability of 1350V and a maximum operating temperature of 175° C. The higher ratings ensure a greater design margin, robust performance, and extended reliability under all operating conditions.
The new STPOWER IH2 series IGBTs also permit increased power-conversion efficiency. Favorable parameters include low saturation voltage, Vce(sat), which ensures low dissipation when the device is turned on.
The freewheeling diode has low voltage drop and optimized turn-off energy that increases the efficiency of single-switch quasi-resonant converters operating at frequencies from 16k to 60kHz.
With their ruggedness and high efficiency, these IGBTs are ideal for induction-heating applications including domestic appliances such as kitchen hobs, inverter microwave ovens, and rice cookers. In a 2kW application, ST’s new IGBT devices can reduce power dissipation by up to 11%.
In addition, the Vce(sat) has a positive temperature coefficient and tight parameter distribution between devices helps simplify design and ease connecting multiple IGBTs in parallel to address high-power applications.
