This application note introduces a variety of Allegro current sensors used for voltage isolation in variable frequency drives. These current sensors help achieve high isolation ratings that meet ...

You can divide the world of electronic motor drives, which control the speed, torque, direction, and resulting horsepower of a motor, into two categories: ac and dc. An ac drive controls ac induction ...

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 ...

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

If you're installing a variable-frequency drive (VFD) or uninterruptible power supply (UPS) — or if you already have this equipment in place — you should be monitoring certain power quality parameters ...

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 ...

Dynamic voltage and frequency scaling (DVFS) techniques — along with associated techniques such as dynamic voltage scaling (DVS) and adaptive voltage and frequency scaling (AVFS) — are very effective ...

According to MarketsandMarkets, The Power Variable Frequency Drive market is projected to reach USD 7.08 billion by 2030 from an estimated USD ...

It is necessary to reduce energy consumption in circuit operations toachieve longer battery life in mobile devices. One new energy reductionscheme is to combine dynamic voltage and frequency scaling ...
