Power and energy monitor checks 0 to 15-V dc supply rails
Linear Technology Corporation introduces the LTC2947 power and energy monitor for 0V to 15V DC supply rails. Most power and energy monitoring ICs use an external sense resistor to measure current. However, choosing a sense resistor is not an easy task, especially when dealing with high currents, where available sense resistors can dissipate too much […]

Video: Difference between arc-fault detection
and ground-fault interruption
There are circuit breakers, circuit breakers with arc-fault detection built in, and circuit breakers with ground-fault interruption built in. And there are breakers with both these features. In this short video at Eaton Corp.’s Power Systems Experience Center, Center manager Dan Carnovale shows what an arc fault really is and how circuitry detects this event. […]
Automatic decay scheme for stepper motor current regulation
by Rakesh Raja and Sudhir Nagaraj || Closed-loop current regulation in stepper motors plays a major role in determining the accuracy and smoothness of motor motion. The scheme of current control also determines the power efficiency of the motor drive system. A typical pulse-width modulation (PWM) control loop used today has a suite of fixed-decay […]
Fuel cell power gains momentum
by Leland Teschler, Executive Editor Hydrogen fuel cells have numerous advantages over the best battery technology for running planes and even heavy duty vehicles. Batteries grab headlines these days, but it increasingly looks as though the power source likely to have the most impact on vehicle technology in the future will be the hydrogen fuel […]
