Low-cost current monitor tracks high dc currents

Susanne Nell @ edn.com has a design idea on how to measure high dc currents. To measure high levels of direct current for overload detection and protection, designers frequently use either a current-shunt resistor or a toroidal core and Hall-effect magnetic-field sensor. Both methods...

Limiting Inrush Current

aimtec.com has a basic article on how to limit inrush current using passive components. Inrush current or input surge current refers to the maximum, instantaneous input current drawn by an electrical device during its initial turn on. Power converters also feature high inrush...

Conventional Flow vs Electron Flow Explained

"baldengineer" explains which way the current flows. A couple of weeks ago I wrote about four current flow direction myths. As a follow up to that popular post, I decided to dedicate this month’s AddOhms electronics tutorial video to Current Flow. In episode #19, I tackle the...

LED current regulator has low dropout

Peter Demchenko @ edn.com This Design Idea circuit regulates the current through one or more LEDs, making it almost independent of supply voltage. Its main advantage is a very small dropout voltage, which can be less than 100mV. The design could find use on LED strips, where the...
