When an application requires changes in motor speeds to meet its objectives, a variable frequency drive (VFD) is often the first thing that comes to mind. This is for good reason—VFDs are typically ...

Variable frequency drives have an Achilles Heel. Even though the VFD itself is protected against damaging electrical conditions, the drive's power cables can fail when subjected to heat or voltage ...

Dublin, Feb. 09, 2021 (GLOBE NEWSWIRE) -- The "Global Variable Frequency Drive (VFD) Market by Type (AC, DC, Servo), End-users (Industrial, Infrastructure, Oil & Gas, Power Generation), Application ...

A Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. These devices, also known as ...

This article presents a reference design for driving a vacuum fluorescent display (VFD) using the MAX15005 power-supply controller in a flyback topology. The design obtains multiple output voltages ...

This is the second half of a two-part article discussing principles and application of the AC induction motors that provide motive power for most of the equipment HVACR engineers specify. In March, we ...
