Geneva, July 12, 2002 -
STMicroelectronics (NYSE: STM) has introduced a family of IGBTs optimized for use in motor control equipment and high-frequency inverters where short-circuit protection is necessary. The parts are based on high-voltage PowerMESH technology, which uses a patented strip layout.
The K family IGBTs offer short-circuit withstand time of 10ms. The devices trade off speed and voltage drop to meet the needs of modern control systems whose operating frequency is higher than in the past, but which also need high efficiency to cut acoustic and energy pollution for industrial and home appliances.
The trade-off between voltage drop (VCE(sat)), switching speed (tfall) and overall power losses has been optimized for a range of frequencies between 5kHz and 25kHz. The use of tailored high-speed, low and soft reverse-recovery charge (Qrr) freewheeling diodes helps reduce EMI and current spikes.
