Two basic IC topologies are employed in dc power sources. If the output is lower than the input voltage, the IC is said to be a step-down, or buck converter. If the output is higher than the input ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) For all signal-chain devices to operate properly, each requires a stable-voltage power ...

Editor’s note: In Part one, we looked at an intro and the basics of linear regulator and switching power supply operation. This final part two will look at design considerations of the switching power ...

Power MOSFETs (Metal-Oxide Semiconductor Field Effect Transistors) are three-terminal silicon devices that function by applying a signal to the gate that controls current conduction between source and ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

In high voltage applications involving tens of thousands of volts, too often people think about the high voltage needed but don’t consider the current. This is especially so when part of the circuit ...
