This article will describe the differences between variable frequency drives and transformers to help you better understand their applications and selection. 1. Inverter VS Transformer Comparison items Frequency Converter (VFD) Transformer Main functions Control motor speed by adjusting frequency Changes voltage without affecting frequency Working principle Convert AC power to DC power first, then convert it to adjustable frequency AC power through inversion Transfers electrical energy between primary and secondary windings through electromagnetic induction to achieve voltage conversion Input power AC input (single phase […]
