by Patrik Kalbermatten, KEMET Engineered composite cores have enabled inductor manufacturers to pack high inductance into a small volume. New FlakeComposite technology takes core performance to the next level, and adds extra mechanical resilience to enable new types of low-profile devices. Power inductors are crucial devices for managing the flow of energy in switching converters, […]
Standard amplifier functions in HEV/EV battery management systems
by Sanjeev Manadhar, Texas Instruments Hybrid electric vehicles (HEVs) and electric vehicles (EVs) are popular because they have low (to zero) emissions and fewer maintenance requirements while offering better efficiency and drive performance. New HEV/EV companies are emerging, while existing automakers are investing more in HEV/EV to compete for market share. The heart of the […]
Advanced circuit protection for connected autonomous vehicles
New protocols for high connectivity need robust protection for reliability and safety. James Colby | Littelfuse, Inc. At the turn of the century, automobiles hosted many electronic systems that were basically independent. Since then, the growth of connectivity and rise of artificial intelligence and machine learning have changed automotive electronics dramatically. Vehicles of all types […]
Keeping connected electronics cool with thermoelectric modules
Future connected vehicles are characterized by clusters of densely packed electronics. Thermoelectric modules can keep the temperature of these hot spots at manageable levels. Andrew Dereka | Laird Thermal Systems Advances in automotive electronics tend to come in small packages where dense circuitry squeezed into a pint-sized footprint generates lots of heat and thermal challenges […]
Want a new perspective on battery management? Buy a plug-in EV.
One facet of EV ownership: Thinking of your daily commute power consumption as equivalent to the sunlight hitting 20 ft2 of your lawn. Rudye McGlothlin, Silicon Labs Earlier this year I took my first step into the EV future by buying a plug-in hybrid electric vehicle (PHEV) – a Chevrolet Volt. A unique car in […]
Varistors ARE viable for surge protection
by Patrik Kalbermatten, KEMET Protecting sensitive electronic equipment against transient voltages in the form of surges that may be either circuit emanating from relays or motors, or significant ESD events such as lightning strikes, is a vital part of equipment design. Several technologies exist to protect sensitive electronic circuitry from voltage surges, including gas discharge […]
Understanding the electromagnetics of real capacitors
by Asem Elshimi, Design Engineer, IoT Wireless Solutions, Silicon Labs Confession: For the longest time, up to my senior year in electrical engineering school, I thought you could find a capacitor on its own. I had such a boundless imagination to think that you could find a circuit element that is purely capacitive in behavior […]
Understanding low-power checks and how to use them
by Aijaz Fatima, Mentor, a Siemens business We live in a shrinking world, and like so much else, the size of ICs is shrinking too. The small size of an IC has many advantages, but it increases the power density of the IC, which leads to many concerns. An IC with a high power density […]
Charging electric vehicles, Part 2: The connections
Part 1 introduced some of the issues related to charging of electric vehicles. Part 2 continues with a look at the hardware (which also involves software, of course). Q: What about the electrical and physical connections? A: There are three connection situations, called “cases”: Case A has the charger connected to the AC mains, and […]
Charging electric vehicles, Part 1: The numbers
It’s nice to envision that recharging an electric vehicle is as straightforward as filling up an internal combustion vehicle, but it’s not: there are multiple charging, power, and connector options as well as limitations. You’re driving your internal-combustion (IC) car, and the gauge indicates it’s time to get “gas” (of course, it’s actually gasoline). So […]
