IGBTs for enhanced variable-speed motor drive performance
18 June 2003
Power Electronics / Power Management
International Rectifier has introduced a new series of 600 V non-punch-through (NPT) IGBTs housed in the TO-220 fully isolated (Full-Pak) package with a guaranteed minimum isolation of 2 kV. The devices are co-packaged with IR's ultra-fast, soft recovery diodes. IR's thin wafer process enables increased electrical and thermal performance. The IGBTs are a part of the IR iMOTION family of integrated design platforms for motion control. The devices can operate up to 175°C junction temperature, increasing the standard operational range by 20% compared to similar products, according to IR. Modulation frequencies up to 20 kHz are possible, enabling better torque control at lower speeds as well as reduced audible noise. Current ratings available include 8, 10 and 15 A, and they have 10 µs short-circuit ratings. Typical applications include variable-speed appliance motor drives in clothes washers, air conditioners and motorised industrial machinery up to 2,5 kW.
