KEC (President Chang-sup Hwang), a company specializing in non-memory semi-conductors, introduced 1100V/30A, 1200V, and 1350V reverse conducting (RC) IGBT (Insulated Gate Bipolar Transistor), in which concentrated reverse conducting diodes are forming a monolithic through their unique trench gate field-stop technology.
Previous IGBTs were in “two-chip, one-package” form in which separated diode chip is installed, but the newly developed IGBT is in “one-chip” form in which diode is installed within IGBT chip itself.
This product is the one to make another advance in the performance of KEC IGBT. It is optimized for soft switching application systems including inverter microwave oven. Compared to the previous products, it lowers switching loss by 30 at most. It allows developers utilize high frequencies up to 60kHz, and such advance enables cost reduction in overall system, as efficiency could be raised to 93percents at most and inductor used in the system could be miniaturized
Guaranteed maximum operative temperature capacity at 175℃ reduced power loss in higher surrounding temperature and provides better reliability. Also, as spike current at turn-on is lowered by 15, stress inflicted on passive elements in the system is reduced, and desirable EMI property could be acquired.
KEC is supplying the introduced reverse conducting IGBT from the 3rd quarter of 2018, and will actively promote occupation of Japanese inverter microwave oven market. The person concerned mentioned that KEC is planning to mass produce 10 million units of the new product annually, and 9 million dollars annual revenue growth is expected.
KEC (President Chang-sup Hwang), a company specializing in non-memory semi-conductors, is an electric component manufacturer company which has been focusing on semiconductor industry for 49 years since its establishment at 1969, and its technical capability has been recognized by prestigious Korean and overseas electronics companies. To keep up with the waves of the 4th industrial revolution, KEC is making changes from consumer market including smart phone and appliances to automotive and industrial semiconductor company and is consolidating the foundation
