When alternating current (AC) prevailed over direct current (DC) in the late 1800s, one of the deciding factors was the need for voltage levels to be raised and lowered throughout the power system to ...

Power-transformer designs minimize weight and cost based on three assumptions: (1) the power source is a sine wave, (2) the frequency is fixed, and (3) the voltage will not exceed a specified maximum.

Remember back…way back, to linear power supplies. Heavy transformers. Big capacitors. As part of my EDN CDEL build, I’ve decided to use just such a power supply as the front end to the two DC-DC PSU ...

This Reinhausen and Factor This webinar contains strategic insights into OLTC retrofit decision frameworks being implemented ...

Neoptix Fiber-Optic Sensors has introduced its T/Guard Direct Windings Monitoring System standard with large backlighted LCD and MODBUS RTU communication. Neoptix T/Guard now features a standard four ...

The use of a copper winding as a temperature sensor for transformer windings is not new. But the circuit presented here goes further. It can make the measurement in-circuit and in real time. The use ...

To investigate the electrical realm of high-frequency and high-voltage, Tesla invented an apparatus that pushed the limits of electrical understanding. None of the circuit's typical components were ...

Those readers who have experimented with winding their own inductors will know that it’s not an easy task, and when those inductors are handling high voltages it can be especially tricky to maintain ...

Sumida Corporation has introduced two new pulse transformers, the CIUH10D46 and CIUH10D47, designed for use in advanced ...
