Tips: Why AFE VFD costs more?
The basic issues with using an AFE (active front end, low harmonic variable frequency drive) are cost and complexity. The cost of the VFD is typically 50 to 100% more than a standard 6 pulse VFD and the complexity (read that as reliability) of the VFD also goes up. An AFE drive replaces the standard diode bridge with IGBTs which not only add components but also requires more processor power. To add insult to injury, the top end of the VFD will have to include an LCL filter which adds more to the cost. Low harmonic multi-pulse front ends require a phase shifting transformer as well as extra diode bridges.
