All regulated power supplies require a feedback link from the output to control the power stage. When isolation is necessary, designers traditionally use an ...

Average current-mode control (CMC) requires that the total waveform of the current be reconstructed for the control loop. This article presents the steps required to select the transformer and how to ...

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 ...

How does the NEC control your signaling and control wiring requirements? Today's industrial facilities use a host of control circuits for motor control, instrumentation signals, and plant shutdown ...

Selecting the right solution to optimize the distribution of power to the connected loads is imperative for maximum system uptime. Switches, breakers, remote signals across Ethernet and automated ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.
