Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

Schemes of alternating current comparators with an adjustable switching threshold are presented, which allow using color-dynamic indication to control the above- and sub-threshold values of ...

As the primary switching device used in a broad range of power conversion applications, MOSFETs play a central role in power supply design. Defining their performance characteristics is crucial to ...

Advancements in power TVS diodes have made them an effective alternative to metal oxide varistors (MOVs) in protecting AC and DC power supplies from power line surges and indirect lightning strikes.
