The Basics of Variable-Frequency Drives EC&M

If an active front-end drive is not suitable for some reason, a passive front-end VFD might be procured. Passive front-end VFDs use multiple phase-shifting transformers and diode bridges to mitigate harmonics. The more pulses a passive front-end VFD has, the fewer problems with harmonics exist.

How do you size a VFD? Flow Control Network

The issue is that the VFD is unable to cool itself as it generates heat while producing current to run the motor. With a high ambient temperature, the VFD is unable to dissipate the generated heat it needs to dissipate and keep itself cool. The sizing may require the need to derate for higher ambient temperature or cool the VFD with cooler air.
