CHAdeMO is the trade name of a quick charging method for battery electric vehicles delivering up to 62.5 kW by 500 V, 125 A direct current via a special electrical connector. A revised CHAdeMO 2.0 s...
In electronics and control system theory, loop gain is the sum of the gain, expressed as a ratio or in decibels, around a feedback loop. Feedback loops are widely used in electronics in amplifiers an...
A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as electromagnet...
UL LLC is a global safety certification company headquartered in Northbrook, Illinois. It maintains offices in 46 countries. Established in 1894 as the Underwriters' Electrical Bureau (a bureau o...
The PMP21495 reference design from Texas Instruments is a 6.6kW, bi-directional, dual-active-bridge resonant converter design that accepts a 380Vdc to 600Vdc input and provides a 280Vdc to 450Vdc out...
Resonant conversion is a topic that is at least thirty years old and where much effort has been spent in research in universities and industry because of its attractive features: smooth waveforms...
A supercapacitor (SC) (also called a supercap, ultracapacitor or Goldcap ) is a high-capacity capacitor with capacitance values much higher than other capacitors (but lower voltage limits) that bridg...
This CUI article provides a good understanding of the differences between NEC Class 2 and IEC Class II power supplies. NEC Class 2 is about output power limiting to ensure no fire breaks out du...
Designs with space-grade devices must consider the variances in values that can occur over time, which is especially true for resistor aging. Designs requiring space-grade components must take...
Electronic equipment uses predominantly positive voltage rails for power; occasionally, some negative voltage rails are also used. For this reason, negative (or inverting) output DC-DC converter so...
Technology trends in artificial intelligence (AI) and the IoT have started to merge, a trend that industry has named the Artificial Intelligence of Things (AIoT). The movement of AI from the cloud ...
In a tunable lighting system, emitted light is detected by a sensor that then sends information to a system controller so appropriate modifications can be made to the correlated color temperature (...
Recently, Zigbee announced that it is working in partnership with other major developers including Amazon, Apple, and Google to create a standard for smart devices. However, is CHIP the right move ...
In a recent press briefing, Texas Instruments (TI) spoke about low electromagnetic interference (EMI) as a key trend in power management, as it minimizes the interference of power supplies with oth...
Learn about everyday grounding systems to reduce common-mode noise. Grounding is the primary method of reducing noise pickup. A good grounding and bonding design can solve a considerable perce...
Learn about the impact of resonance in grounding and bonding conductors. When dealing with grounding and bonding with high-frequency signals, the conductors’ impedance is of paramount importan...
