Hi,
Mind: You don´t pay for apparent power, but you pay for real power.
I should pay for real power if i operate any equipment otherwise it will become illegal !:lol:
For PFC application, capacitors are being used. in VFD, the capacitors are used in DC bus to perform PFC. So without adding extra equipment this power factor correction can be made. These attributes of variable frequency drive tempt the industries to choose it and enjoy extra savings in terms of energy and fewer losses
