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...
BTU (British Thermal Unit) is a measure of energy defined by the amount of energy require to change 1 pound of water by 1 degree Fahrenheit. For our purposes we use BTU/hr as a measurement of work ...
Today, we’ll be looking at a topic that often confuses people who are new to cryptocurrency —Token vs Coin. Sometimes people use the term “coin” to refer to what other people call “toke...
Abstract: Modern DC-DC converters use PWM controllers with integrated MOSFETs to achieve the highest power density for DC-DC modules. Since the power MOSFETs are inside the PWM chip, they can signi...
Designers using modular power converters for their systems know how critical a thermal derating curve is to the success of their design. No offense to marketing people, but the bulleted features on...
Hot swapping is replacing or adding a device without stopping or shutting down the system. Hot plugging on the other hand describes only the addition of components that would expand the system with...
The Moisture Sensitivity Level (MSL) indicates the floor life of the component, its storage conditions, and handling precautions after the original container has been opened. The permissible time ...
With each passing year, new cars get more complicated and high-tech. The new higher power requirements associated with these advancements—along with ever-stricter emissions regulations—are why&nbs...
Writer: Ron Knight (Chemist) Aluminum being the most abundant metal in the earth’s crust (at 8.2% of the total metals) is never found free in nature. Aluminum is reactive and will react ...
