Continental announces new generation of power electronics

While batteries and motors tend to get most of the press, a vehicle’s power electronics is just as important to the overall efficiency of a powertrain, and thus to its range and performance. International automotive supplier Continental, which produces power electronics components for five European automakers, has announced that its next-generation system will enter series production… Read more »

The future of integrated inverters: Press-fit solderless interconnects and smarter design

Interplex, the complex assemblies expert, on power electronics, the automotive industry and the continuous drive for smarter design Power modules containing high-power insulated-gate bipolar transistors (IGBTs) are at the core of most modern inverters. These modules are the electronic muscle of the system. They perform all the switching, and they generate all the heat. But… Read more »

Siemens saves weight and space with integrated motor and inverter

Screw it in and drive Among the companies pushing the boundaries of packaging efficiency is the German engineering colossus Siemens. The company has developed an integrated motor and inverter contained in a single housing, the Siemens Sivetec MSA 3300. The new drive unit reduces weight, frees up six to seven liters of additional space, lowers… Read more »

UK startup improves free piston linear technology, generating power with no drive shaft

A free piston linear power generator (FPEG), which uses combustion to generate electricity directly, using no drive shaft, could provide an EV range extender that’s far smaller and more efficient than a legacy ICE. Several research groups, including a Toyota R&D team, are investigating this intriguing technology. UK startup Libertine LPE has developed an FPEG… Read more »

Toyota tests silicon carbide power semiconductors in a hybrid Camry and fuel cell bus

Power semiconductors are key components of the power control units (PCUs) used in all types of vehicles with electric powertrains – EVs, hybrids and fuel cell vehicles. Current power semiconductors are leaky, accounting for around 20 percent of a vehicle’s electrical losses, so raising their efficiency could be a rewarding area of study. Toyota has… Read more »
