DTF and SBE Partner on High-Temp DC Link Caps for WBG Semis

May 09, 2017 by Jeff Shepard

DuPont Teijin Films and SBE Inc. announced collaboration to bring the power electronics industry a new level of dc link performance, high temperature and high density capacitor solutions. Under this collaboration, DuPont Teijin Films (DTF) is announcing that for high voltage, high power solutions, SBE will be the exclusive supplier of capacitors for these applications using DuPont Teijin Film PEN HV film for compatible sizes of SBE's unique Power Ring technology. SBE is concurrently announcing that it will exclusively use DTF's PEN HV film for all high performance high temperature applications in this expanded temperature range.

New wide bandgap (WBG) semiconductor technologies such as SiC allow for much higher temperature applications for next generation power converters. The combination of these leading edge technologies from DTF and SBE will allow advanced customers to fully optimize solutions across new platforms and efficiency goals.

DuPont Teijin Films PEN HV film allows SBE to provide capacitors with comparable electrical characteristics to Polypropylene film but with much greater operating temperature range above 125 degrees C. The recently commercialized dielectric PEN HV for power capacitors combines high temperature capability to excellent electrical strength and self-healing properties with the highest energy density and is optimum for use in advanced power state of art conversion modules.

SBE Power Ring Technology achieves the industry’s highest level of current density and allows customers to utilize the highest usable voltage for their semiconductor strategy. Combining SBE’s proven performance with DuPont Teijin Films PEN HV film will allow customers a broader temperature range of applications to reliably implement these solutions.

“DuPont Teijin Films is delighted to start cooperation with SBE to combine PEN HV dielectric for high temperature power applications to SBE’s innovative capacitor manufacturing technology in order to allow development of highly efficient power conversion technologies.”

“SBE is pleased to be working exclusively with DuPont Teijin Films for advanced high temperature applications. We believe that this collaboration is the beginning of an important product and market development for advanced applications for the future power conversion systems. Our customers will achieve their goals with the results.”
