The basic function of a variable speed drive (VSD) is to control the flow of energy from the mains to the process. Variable speed drives sit between the electrical supply and the motor. Power from the electrical supply goes into a drive and the drive then regulates the power that is fed to the motor.
The difference with Soft Starter vs Variable Frequency Drive (VFD) is the method of starting employed. A soft starter reduces voltage, not Hertz, and as such the starting …

Internal Workings of a VFD. VFDs have three main components: – Rectifier – Filter – Inverter. The Rectifier acts like Diodes, takes the incoming AC voltage and changes it to DC voltage.. Next, the Filter uses Capacitors to clean the DC voltage making it a smoother incoming power.. Finally, the Inverter uses transistors to convert the DC …
The soft starter estimates the motor's speed throughout each AAC start and stop, and adjusts power to the motor to provide the selected acceleration or deceleration profile.
