Infineon presents latest power modules for hybrid and electric vehicles; compact and higher power density
May 11, 2016
Infineon Technologies AG is presenting its latest power module family for hybrid and electric vehicles—HybridPACK Double Sided Cooling (DSC)—at the PCIM 2016 tradeshow. The new power modules have extremely small dimensions of only 42 mm x 42.4 mm x 4.77 mm. They target HEV applications such as main inverters and generators with a typical power range of 40 to 50 kW. In order to support higher power, they can be used in parallel configurations.
With only 15 nH, the stray inductance is very low while blocking voltage was increased to 700 V. Both factors support the development of inverter systems with reduced switching losses of about 25% and very high efficiency.

Study finds EV use-phase fuel savings exceed marginal increase in energy demand for WBG semiconductor manufacturing by 2 orders of magnitude
August 14, 2015
Power electronics semiconductors, which manage voltage and current, are a key technology for enabling improvements in “fuel economy” in electric vehicles. While conventional silicon-based semiconductor technology currently owns the plug-in vehicle power electronics market, emerging wide band gap (WBG) semiconductors offer significantly greater energy efficiency potential than silicon.
A team from Oak Ridge National Laboratory, Argonne National Laboratory, Northwestern University and the US Department of Energy (DOE) has now estimated the potential energy benefits in electric vehicles for two leading WBG semiconductor architectures—silicon carbide (SiC) and gallium nitride (GaN)—and compared those with conventional silicon. Their paper is published in the ACS journal Environmental Science & Technology.
