A grouping of Mitsubishi Electric’s AC drives or variable frequency drives (VFDs). In the competitive landscape of machine design, engineers in food, pharmaceutical and manufacturing sectors face the ...

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% ...

Although much has been published on variable-frequency drives (VFDs), people continue to be confused by them. The intent of this article is to provide a basic overview of these devices by evaluating ...

Many power ICs use frequency jitter, which spreads a control signal's spectrum, to control EMI (electromagnetic interference). If you need to add frequency jitter to power ICs that control three-phase ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

Teledyne LeCroy’s MDA8000 series of motor-drive analyzers performs three-phase power-analyzer static (steady-state) calculations, dynamic three-phase power and mechanical motor analysis, and ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

This single stage, 3-phase power line filter family targets low to midrange power inverters as well as other chassis-mounted applications that require high insertion loss performance in a compact ...
