PWM Converter

PWM Converter is synonym of Active Front-end Converter. As the PWM Converter is connected at the input side (front side) of the AC drive, it is also known as an Active Front-end Converter.

Active Front-end Converter is used to improve the power quality by improving the power factor to unity (also settable) and reduced current harmonics at input side. Also, it allows bi-directional power flow; the excess energy can be feedback to the grid (regenerative braking) rather than dissipating in resistors.

Frequently asked questions

Why PWM Converter?

To have unity power factor and reduce harmonic content at supply side of the AC drive. If load is regenerative as in case of centrifugal lift, Triton drive, paper industry, wire - winding then one can use PWM converter or active front-end converter at the input of inverter to make a four-quadrant drive.
