Ideal Power’s double-sided B-TRAN power semiconductor devices
Power conversion specialist Ideal Power (NASDAQ: IPWR) has produced prototypes of a new product called a Bi-Directional Bi-Polar Junction TRANsistor (B-TRAN). Due to its anticipated low conduction and switching losses, Ideal Power believes the B-TRAN can improve the efficiency of a range of power control and conversion equipment, including EV drivetrains. The company expects the… Read more »
Eaton’s new Bussmann series EV fuses
Power management giant Eaton has introduced its new Bussmann series EV fuses, which are specifically designed to protect sensitive electric and hybrid automotive equipment, including high-capacity batteries, power conversion equipment, contactors, cabling and other auxiliary circuits. With protection as low as 135% of rated current, Bussmann series EV fuses can protect a wide range of… Read more »
Researchers use wide-bandgap material to make inverter smaller and lighter
Researchers at North Carolina State University have developed a new type of inverter that offers superior efficiency in a smaller and lighter package than current models. Conventional inverters rely on components made of silicon. The NC State team has developed an inverter using off-the-shelf components made of the wide-bandgap semiconductor material silicon carbide (SiC). “Our… Read more »
TDK and Toshiba establish joint venture for automotive inverters
Japanese conglomerates TDK and Toshiba have agreed to establish a joint venture to manufacture automotive inverters for hybrids, PHEVs and EVs. With an eye on the global trend toward stricter emissions regulations, TDK is strengthening its energy unit business, which centers on power conversion hardware, and the controlling software, for electrified vehicles. TDK’s line-up includes… Read more »

Researchers increase energy density of cathode by controlling oxygen activity
An international team of researchers has demonstrated a new way to improve the performance of lithium-rich cathode materials by creating oxygen vacancies at the material’s surface. In “Gas-solid interfacial modification of oxygen activity in layered oxide cathodes for lithium-ion batteries,” published in Nature Communications, Minghao Zhang and colleagues explain the importance of oxygen atoms in… Read more »
Silicon-carbide power electronics enable new ZapCharger Portable charger
Norwegian power electronics firm Zaptec has developed a new portable charger in partnership with Renault. The ZapCharger Portable is designed to be compact (3 kg, 45x10x10 cm), rugged and smart – it’s waterproof, operates at temperatures from -40° to 55° C, and continuously monitors the grid to shut down immediately if it detects a fault….

Model 3 mania has increased demand for other Tesla products
The tidal wave of reservations for Model 3 carries both good and bad news for Tesla – it’s cool to have all those future sales in the pipeline (over $14 billion worth, the company figures), but it’s a bummer to have to wait two years to get the cash. However, all the publicity comes with… Read more »
Argonne: EVs may be almost as energy-dense as gasoline vehicles by 2045
Hydrocarbon fuels have energy densities that are at least 100 times greater than that of current lithium-ion batteries. Even with projected improvements in battery technology as far out as 2045, batteries are still expected to be significantly less energy-dense than gasoline. However, the energy density of the actual storage medium may not be the best… Read more »
