WEG Frequency Inverters

Frequency inverter also called frequency converter, it is a power control conversion device to convert normal power supply (50Hz or 60Hz) to another frequency power by inner power semiconductor on/off behaviors, to control electric motors in variable speed operations. Variable frequency control is changing the frequency supply to the motor stator windings to achieve variable speed control purpose.

of WEG Variable Frequency Drive.

The frequency inverter is mainly consisted of rectifier (AC to DC), filter, inverter (DC to AC), braking unit, drive unit, detection unit and micro processing unit etc. The control circuit controls main circuit, the rectifier circuit converts AC power into DC power, DC intermediate circuit smoothing the rectifier circuit output, then the inverter circuit reverse DC current into AC current again.
