Specifics about high-power-density motors (HPDMs). Applications best served with HPDMs. Why BLDCs are perhaps the most preferred among HPDM architectures. High power density is an important ...

Power management plays a major role in virtually every electronic system because it controls, regulates, and distributes dc power throughout the system. Therefore, the dc power management subsystem ...

This document teaches the users to determine the characteristics of step-down DC-DC (buck) switched mode power supply through understanding and exploring its voltage and current waveforms. Both the ...

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, ...

Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of ...

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 ...

You almost never hear of a DC Watt Meter – one just does some mental math with Volts and Amps at the back of one’s head. An AC Watt Meter, on the other hand, can by pretty useful on any workbench.

When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, ...

The power supply circuit is a ubiquitous component in all electronic devices, regardless of whether they are powered by batteries or by direct or alternating external electricity. The whole ...
