With the AF1000 variable frequency drive (VFD), this company has introduced a cost-effective solution for basic drive ...

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 ...

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 ...

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 ...

OEMs and hobbyists benefit from technology’s trickle-down effect. Figure 1. Many industrial applications and small machines with a motor and limited I/O requirements can benefit from using AC VFDs with ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...

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 ...
