The harnessing of electricity has played a pivotal role in human history and has exponentially expedited our growth as a species. Since becoming a household commodity in the late 19th century, ...

High power density is an important characteristic in most motors, even in a tiny motor with a high-power-output capability. A high-power-density motor (HPDM) is one that has a high ratio of ...

The article provides details on device types such as dc supplies, converters, transformers and protection devices used in ...

In Part 1 of this two-part series, we explored PLC basics and voltage sag susceptibilities. In this segment, we present PLC voltage sag test results along with guidelines for making PLC systems more ...

Power over Ethernet (PoE) is not rocket science, but it’s not plug-and-play magic either. This short primer walks through the basics with a few practical nudges for those curious to try it out. It’s a ...

Battery input (portable equipment) - Because of the size and weight restrictions of portable equipment, this power-management subsystem is usually integrated with the rest of the electronic system.

This course introduces more advanced concepts of switched-mode converter circuits. Realization of the power semiconductors in inverters or in converters having bidirectional power flow is explained.

You may have seen the Ruideng range of programmable power supply modules from China: small and relatively inexpensive switch-mode buck converters, with microprocessor control and a front panel ...

Increasing numbers of boaters are turning to lithium-iron-phosphate (LiFePO4) batteries to power house circuits and electric trolling motors. This brings up a question: Can boaters effectively ...

There has been a significant increase in integration of high-performance radio transceivers suitable for applications such as cellular base stations and radars. These transceivers use two different ...
