Using constant current control for metal purification
In the vast world of power supply applications, we can identify two main categories for regulating the power applied to the load. The first is ‘constant voltage’, where the control loop maintains a constant voltage to varying load current demands; the second is ‘constant current’ where the current is maintained constant to vary the voltage applied to the load. Giacomo Mazzullo of TDK-Lambda explains.

Angle sensors: do you know your arc-seconds from your gradians?
Angle sensors are generally rated and, just as importantly, priced according to their measurement performance. But performance is stated in a variety of ways and some manufacturers confuse matters by using crafty ‘spec-manship’. Mark Howard of Zettlex explains some of the terminology and provides an explanation of how to specify an angle sensor that is right for your application.
