A resistor doesn't have a power factor. However, if a circuit is pure resistance in nature the power factor will be one when a voltage is applied and a current flows in the circuit. The power factor is a measure of the relative phases of the current and voltage in a circuit.
The power factor of a purely resistive circuit is 1.0.
using vienna rectifier
A block diagram of SMPS has a main filter, primary rectifier, and power switch. It also has an output transformer, secondary rectifier, smoothing circuit, and controller.
It removes the remaining AC ripple after the rectifier, using capacitors (to bypass it to ground) and/or inductors (to block it).

power factor means kw/kva
power factor means kw/kva

using vienna rectifier
ratio between true power and apparent power is called the power factor for a circuit Power factor =true power/apparent power also we conclude PF=power dissipated / actual power in pure resistive circuit if total resistance is made zero power factor will be zero
Ripple factor ripple factor is very important in deciding the efficiency of the rectifier .ripple factor give the total power converted AC input to the DC output. Ideal ripple factor should be zero and power factor 1. Ripple factor of half wave rectifier 1.21 and full wave rectifier is 0.48.

rectifier circuit convert ac to dc signal

power factor=real power/apparent power... real power in the sense the capacity of the circuit for performing a work in a particular time..for example the work done by a motor circuit is so and so...real power is what we consume from them... apparent power if the product of the current thro' the circuit and the voltage...it will be always greater than the real power.. if the POWER FACTOR IS 1.0(100%),THEN THE AC POWER IN THE CIRCUIT WILL BE EQUIVALENT TO THE POWER OFFERED BY A DC CIRCUIT....
