Allegro MicroSystems Inc. has introduced the ACS704 family of Hall-effect magnetic field sensors in SOIC8 packaging, with the current path integrated into the package for better sensitivity and ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

Miri is a creative writer with a passion for gaming and animation. She started gaming way back in 1994 on the Super Nintendo and Sega Genesis and has been a console gamer ever since. She's currently a ...

Motor control circuits in appliances including refrigerators, washing machines and air conditioners, need to operate more efficiently, reliably and safely while meeting cost requirements. With energy ...

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into the ...

As systems extend and expand the exploitation of the latest power semiconductors (IGBTs, MCTs, etc.) that manifest the very relentless advance in power output limits, a prerequisite (and parallel) ...

Two of the most widely used approaches for current sensing have shortcomings that limit their use in highly integrated power electronics applications. Hall-effect current sensors use a flux ...

What Is The Hall Effect? Discovered by Edwin Hall in 1879, the Hall effect is a phenomenon when voltage (potential difference) is generated across a current-carrying conductor when it is placed in a ...

In one sentence: The spin Hall effect is a phenomenon in which an ordinary electric current flowing through a non-magnetic conductor with strong spin-orbit coupling creates a sideways spin current, ...

The dream of levitating an object with ultra-low power consumption has been a long-standing one. The rapid advancement of rare-earth magnetic materials in recent years has made the ...
