When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

The project intends to create a sprinkler controller that can be used as an interface wherein system valves or zones will be managed. A perfboard with wire wrap for the control/logic portions can be ...

A new set of EDA tools from TriQuest Design Automation lets you design optimized on-chip controller circuits before synthesizing to the gate level. The tool set comprises the TriQuest Controller ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system ...

Medium- and high-voltage systems that range from 9 to 72 V often require one or more of the following circuit capabilities: hot-swap control, circuit-breaker fault protection, and inrush current ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

Per 2014 NEC Article 100, short circuit current rating (SCCR) is defined as: “The prospective symmetrical fault current at a nominal voltage to which an apparatus or system is able to be connected ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...
