C& H Technology, Inc and International Rectifier Introduces
Cooler-Running High-Speed, Isolated Rectifier-
IGBT Modules for Compact, High-Current Applications
December 2002 --
EL SEGUNDO, Calif. - International Rectifier, IRź (NYSE: IRF),
today introduces the MTP Switch family of isolated modules insulated with a
ceramic aluminum nitride layer for improved junction-to-case thermal resistance.
The insulation layer enables as much as seven times better thermal conductivity
(cooling capability) than alumina substrates used in competing devices. The new
600V- and 1200V-rated modules combine high-speed IGBTs with optimized diodes to
form single-package, space- and assembly-cost saving alternatives to discrete
solutions. The new modules are designed for high current industrial power
supplies used in high frequency arc welding machines and uninterruptible power
supplies (UPS).
"The MTP Switch
family modules feature enhanced thermal characteristics to reduce size, and low
connector inductance and resistance to improve high-speed operation, said Dr.
Francesco Vallone, International Rectifier Product Marketing Manager.
Technical Highlights
The 50MT060ULS is a
fully-insulated low-side chopper module, made with an International Rectifier
Ultrafast IGBT and a HEXFREDź diode with ultrasoft reverse recovery current.
The 50MT060WH is a
fully-insulated half-bridge module built with a pair of IR's WARP Speed(tm)
IGBTs in parallel and a HEXFRED freewheeling diode with UltraSoft reverse
recovery current characteristics. This double-IGBT layout enables efficient
power dissipation and current sharing.
Two additional MTP
Switch modules are available, with 1200V ratings. The fully-insulated 20MT120UF
full-bridge and the 40MT120UH half-bridge modules host 1200V-rated IGBTs. The
1200V devices can be directly connected to the DC bus in the majority of
three-phase systems. The half-bridge module is available with on-board
temperature monitoring.
