Power Module for Electric Vehicles

Mitsubishi Electric (Tokyo, Japan) recently introduced a transfer molded power module (T-PM) designed for hybrid and electric vehicle applications. The J-Series T-PM, incorporating proprietary technology that ensures power loss reduction, has a lifespan 30 times longer than industrial power modules and is also Pb-free - including the terminal plating.

Capturing and Using Waste Heat from Cars, Factories, and Power Plants

New technology is being developed at Oregon State University to capture and use the low-to-medium grade waste heat from automobiles, diesel generators, or factories and electrical utilities. The new systems should be able to use much of that waste heat either in cooling or the production of electricity.

Neutron Analysis Explains Dynamics Behind Thermoelectric Materials

Neutron analysis of the atomic dynamics behind thermal conductivity is helping scientists at the Department of Energy's Oak Ridge National Laboratory (ORNL) gain a deeper understanding of how thermoelectric materials work. The analysis could spur the development of a broader range of products with the capability to transform heat to electricity.

Isolated Monolithic Flyback Regulator

Linear Technology Corporation (Milpitas, CA) offers a high-reliability (MP-grade) version of the LT3511, a high-voltage isolated monolithic flyback regulator that operates over a -55°C to 150°C junction temperature range. The device simplifies the design of an isolated DC/DC converter since it needs no optocoupler, third winding, or signal transformer for feedback, as the device’s output voltage is sensed from the primary-side flyback signal.

Researchers Counteract Biofuel Toxicity in Microbes

Advanced biofuels are highly touted as potential replacements for gasoline, diesel, and jet fuels. Equally touted is the synthesis of these fuels through the use of microbes. However, many of the best candidate compounds for advanced biofuels are toxic to microbes, which presents a “production versus survival” conundrum.

Cool and Green: Vehicle Thermal Management

Air conditioning is a ‘must-have’ for most new cars. But the fluorocarbon refrigerant HFC-134a – the global standard – is one of the ozone-depleting greenhouse gases causing global warming. With these concerns, the European Union has passed regulations phasing out the compound beginning in 2011 and mandating the use of alternatives with less environmental impact.
