VFD switching frequency refers to the rate at which the DC bus voltage is switched on and off during the pulse width modulation (PWM) process. Harmonic distortion occurs when a VFD converts power from an AC to a variable frequency output to a motor. The harmonics occur as the transistors rapidly turn on and off at a rapid speed. Harmonic distortion in a drive can be reduced by increasing the speed the at which the IGBTs operate to get a cleaner sine wave for better motor operation. ► Learn more about VFD Switching Frequency: https://kebblog.com/vfd-switching-fre... ► Subscribe to Our Channel Here: / kebautomation -- Follow KEB America Here -- Website: https://www.kebblog.com LinkedIn: / keb-automation-kg Facebook: / kebamericainc Twitter: / kebamerica Instagram: / keb_america
