Silicon carbide on the road to automotive electrification

  The automotive industry has long been focussing on the higher efficiency of the combustion engine and electrification of the drivetrain in hybrid and fully electric vehicles to meet CO2 emission goals. Now we finally see a tipping point with a greater availability of SiC (Silicon Carbide) chips that offer extremely low power losses and higher temperature resistance.

Smart energy storage will define the future of everything

From smartphones to automobiles and the electric grid, energy storage is becoming more critical. For mobile devices, the need is clear for safe, longer lasting, energy dense chemistries. For automobiles, the move to hybrid, electric, and autonomous vehicles has increased the bounty to be had for denser and lighter storage. As for the electric grid, it stands to benefit from load balancing using a combination of the IoT (smart grid) and local...

Qi-certified medium power transmitter reference design

  Apple touts its new Airpods as wireless, effortless, and magical, a description that aptly fits another emerging technology: wireless charging. Wireless charging sends a flow of electrons to a device’s battery using either ultrasound, solar, or electromagnetic energy, in place of a tethered AC charger.

Chipmakers warming up to 48V datacentre movement

  With the emergence of 48V datacentre architecture on the server rails, is there a greener cloud on the horizon in 2017? A lot depends on the availability of chips that can efficiently facilitate the 48V single conversion to the PoL (Point of Load) while providing the projected 16x reduction in distribution loss and 30% lower conversion loss.

High voltage ICs give designers an advantage they can appreciate

  It’s not easy being tasked with designing a 'better' DC/DC buck converter, which must transform a lightly regulated DC voltage into a tightly regulated source for motors, industrial equipment, and communications infrastructure; as always, the objective is higher efficiency, but without any penalty in size, complexity, or performance.

Reference design for drone motor controller

  The ability to quickly change the speed and rotational direction of its motors is the key to a drone’s performance, which makes the ESC (Electronic Speed Control) module a very important subsystem. Faster motor speed changes also make for greater stability, which saves energy thereby enabling longer flight times.

Calculating the accuracy of a battery fuel gauge

  A battery fuel gauge obtains data from the battery to determine how much juice is left. Do not misconstrue gauging accuracy for measurement accuracy. A gauge’s ability to accurately report state of charge (SOC) and predict remaining battery capacity depends on measurements including voltage (‘V’), current (‘I’) and battery temperature (‘T’).
