CR4 Thread: Drives Energy Efficiency (Cyclo, LCI, or VSI)
Aug 30, 2010· Power factor and efficiency are not the same thing. Efficiency is the ratio between the output power from the drive and the input power to it. The difference between these is the power needed by the drive to operate itself. Power factor is the relationship between the voltage waveform and the current waveform in a circuit.
