⚡ AFE Technology (Sine-Wave Rectifier THDi <3.0% vs 18-Pulse Transformer Drive)

Active Front End (AFE) vs 18-Pulse VFD Calculator

Compare IGBT-switched Active Front End (AFE / Rockwell PowerFlex 755T / Siemens SINAMICS) regenerative variable frequency drives versus bulky 18-pulse multi-winding transformer drives: achieve near-unity power factor ($PF > 0.98$), keep total input current distortion strictly below 3.0% THDi, eliminate 40% equipment footprint, and drive profits.
