An electric car designed by engineering students at the University of New South Wales in Australia has established a new record for single-charge travel for high-speed electric vehicles. The hybrid solar-powered Sunswift vehicle -- whose solar panels were switched off for this test -- traveled over 500 km at an average speed of more than 100 km/hr on a single battery charge, breaking a 26-year-old world speed record.
A cutaway image of the Sunswift eVe hybrid solar electric vehicle, which is claimed to offer a range of up to 800 km (~500 miles) on a single charge and a top speed of 140 km/h (87 mph), making it practical for day-to-day use.
The car's designers are hoping the test demonstrates that the car is ready for practical use, and expect the vehicle -- called the Sunswift eVe -- to meet Australian road registration requirements in as little as a year, which would make it the first street-legal solar-powered vehicle. While obvious comparisons are being made with Tesla, the eVe seats only two people, has a carbon-fiber body that weighs only 661 lbs, and doesn't offer many standard features found in production vehicles.
In product news, Keithley Instruments has announced programmable power supplies that are also measurement instruments. The 60-V 3.2-A 2280S Precision Measurement DC Power Supply can source stable, low-noise voltages as well as monitor load currents over a wide dynamic range from amps to nanoamps.
Texas Instruments has expanded its line of multi-channel buck converters. The triple-output TPS65261 and TPS65262 synchronous switching regulators accommodate an input range of 4.5 to 18 V and offer outputs of 3/2/2 A and 3/1/1 A, respectively.
Intersil has introduced a synchronous buck controller outfitted with 3-A high-side and low-side drivers and offering high step-down efficiency. The ISL78268 is designed to support virtually every 12-, 24-, and 48-V high-current buck requirement in automotive and industrial applications.
A new buck-boost controller from Linear Technology features a -55°C to 150°C operating junction temperature range. The 80-V LT8705 offers up to 98% efficiency and operates from input voltages above, below, or equal to the regulated output voltage.
Kemet has introduced a supercapacitor development kit to complement the company's S301 screw terminal supercapacitor. The Supercapacitor Development Balancing Kit contains enough balancing cards, bus bars, screws, washers, and wire to assemble six S301 60-mm-diameter cells.
Finally, Cadence has announced a transistor-level electromigration and IR-drop power integrity tool. The Voltus-Fi Custom Power Integrity Solution delivers foundry-certified SPICE-level accuracy in power signoff to speed overall design closure.
