Pushing the power limits: Fuji Electric on the new requirements of power electronics
With each passing model year, the requirements demanded of automotive power electronics increase. Market forces are pushing Insulated Gate Bipolar Transistor (IGBT) modules towards lighter, smaller, more powerful and more reliable technology. These switching devices are what power an EV or hybrid inverter, and with increasingly stringent emissions requirements, automakers are looking for more innovative… Read more »
EVs, renewables & energy storage: The unstoppable trio of energy’s future
The ripples of disruption: Q&A with Mike Calise The concept of disruption is often discussed in the fields of semiconductors, the internet, data, computers and software. But what about the energy industry? The world has been largely generating and consuming energy the same way for over a century. Charged talked to Mike Calise, Head of Electric… Read more »
Hitachi supplies inverters and DC/DC converters for Mercedes PHEVs
Hitachi Automotive Systems has begun to supply Daimler with compact, high-output inverters and DC/DC converters for use in the Mercedes S500 and S550 plug-in hybrids, which recently went on sale in Germany. Hitachi developed a third-generation inverter that is 40% smaller and offers higher output than the previous version, and a high-output DC/DC converter with… Read more »
Siemens saves weight and space with integrated motor and inverter
The latest idea for reducing vehicle weight comes from the German engineering colossus Siemens, which has developed a way to integrate an EV’s motor and inverter in a single housing. An inverter, which converts the battery’s direct current into alternating current for the motor, is a key component of any EV. Siemens’ Sivetec MSA 3300… Read more »
New imaging technique gives researchers an unprecedented look at the inner workings of batteries
Scientists around the world are testing new ways to look inside lithium-ion batteries to gain a better understanding of what happens during charging and discharging. A team of chemists and engineers at Ohio State University claims to be the first to use Neutron Depth Profiling (NDP) to track the flow of lithium ions into and… Read more »
Membrane technology and the importance of venting EV electronics
Protecting a car’s sensitive electronics throughout its lifetime is a must, whether it’s a conventional ICE vehicle or an EV. However, the larger electronics in plug-in vehicles have more power, more heat and higher pressure differentials that present new technological challenges to OEMs and suppliers. Any power semiconductor inevitably generates heat while conducting current, due… Read more »
