Figure 1 A series diode protects systems from reverse polarity but wastes power in diode losses. Figure 2 You can use a bridge rectifier so that your system works no matter what the input polarity is.

Most test setups need only positive voltages to power the device under test (DUT). Some devices require negative voltages as well. Test voltages aren’t always fixed, though. Their value and/or ...

The Barrington Model Circuit Breaker Simulator was designed to be a convenient, lightweight alternative to operating high-voltage circuit breakers while testing the operation of substation protection ...

Sometimes, the most unexpected detours lead to the most interesting discoveries. After a brief break, I found myself revisiting latching relays—not just as components, but as puzzles waiting to be ...

As they took him away, Clyde realized that leaving out that protection FET to save $0.35 had been a poor design decision. (Courtesy of Autoevolution) Electronics and automobiles have a long history ...
