“An AFE uses PWM with a high-carrier fre-quency, the switching losses are higher compared to the block-style commutation of the regen unit. The PWM iron losses in the AFE filter are also higher compared to those in similarly sized harmonic filters. AFE systems can only be connected to a balanced three-phase wye, center grounded electric system; delta-connected systems are not permissible.”
“A regenerative unit can be used in lieu of a braking resistor, and the regenerated power can be returned to the grid, where it is consumed by other building loads. Regen units are becoming increasingly popular, as they can dramatically increase system efficiency and lower the total cost of elevator ownership. Since the regen’sIGBTs switch the current into the line in a similar manner to the diodes in a six-pulse rectifier, a regen unit will have similar harmonic content during regen mode as a VFD.”
