Dual-component power converter

Premo has developed an 11 kW power converter using its patented technology that integrates multiple magnetic components (writes Nick Flaherty). The 3DP-11KWHVHV combines a full-bridge 150 µH LLC resonant transformer and 25 µH resonant choke in a single unit. This cuts the volume of the converter by up to half, and can reduce the amount of […]

Koenigsegg announces its first e-motor and EV drive unit

Koenigsegg has unveiled its first e-motor, the Quark, which uses a torque/power-rich balance between radial (power-dense) and axial (torque-dense) flux topology it calls Raxial Flux. The company has also integrated two of them with one of its David inverters, plus planetary gearsets, to create a torque-vectoring EV drive unit it calls the Terrier. The company says a key […]

Inverter integration cuts size, weight

Texas Instruments has integrated a transformer into a gate driver to enable distributed switch architectures for inverters (writes Nick Flaherty). The UCC14240-Q1 isolated DC-DC bias supply module integrates the transformer and components with 3.5 mm-high planar magnetics to reduce the size, height and weight of a distributed power system in an inverter. The integration of […]

Schaltbau launches arc-quenching high-current DC contactors

Switching large direct currents safely and responsively is a critical task in EV drive systems, requiring electromagnetically controlled contactors that extinguish the unwanted arcs that inevitably form between the main contacts when they open (writes Peter Donaldson). Drawing on almost a century’s experience in the railway industry, German company Schaltbau is addressing this issue by […]

Feinmetall launches high-current contacts for battery testing and production

As currents produced by EV batteries get higher, the demands placed on the contacts in the systems used to check cell, module and general battery performance in testing and production are also increasing. High-performance contact probes are therefore growing in importance (writes Peter Donaldson). To that end, contacts manufacturer Feinmetall has launched a family of […]

Inverter sintering set to boost range

MacDermid Alpha Electronics Solutions is working with STMicroelectronics on improved sinter technology for EV inverter assemblies. The process, known as pressure sintering, can significantly increase vehicle efficiency and range as well as lowering production costs (writes Nick Flaherty). Pressure sintering provides much lower thermal resistance in an inverter, which leads to better power cycling and […]

Cressall unveils liquid-cooled brake resistors

In electric and hybrid vehicles, regenerative braking is a very effective means of recovering energy by recharging the battery, but sometimes it recovers more energy than the battery can accept (writes Peter Donaldson). This is particularly true for large vehicles such as trucks, buses and off-highway machines on a long run downhill that start with […]

BorgWarner launches high-altitude charging station

With charging capacity increasingly seen as a limiting factor in the growth of EV markets around the world, BorgWarner Systems has been sharing more details about its new Iperion 120, a 120 kW charging station designed to form the heart of its efforts to create modern charging infrastructures (writes Peter Donaldson).   A key feature […]

New chapter in the story of cork

Finding a material with several applications in state-of-the-art EV powertrains that literally grows on trees might seem unlikely, but that is exactly what Portuguese company Amorim Cork Composites is offering with cork (writes Peter Donaldson). The raw material is the bark of the cork oak tree (Quercus suber), which in addition to its best-known application […]
