Capacitor Choke
Chokes do not correct power factor in the usual sense of "correcting" or the usual sense of "power factor." Motors that are directly connected to mains power have a low power factor because they are inductive. To compensate or "correct" that, capacitors are used. ...

What Is A Filter Circuit
The circuit of a choke input filter consists of a choke L connected in series with the rectifier output and a filter capacitor C, which is connected across the load resistance R L. Here in this fig.3(i) only a single filter section is shown.
Power Factor Correction (PFC) Explained | Article | MPS
This current also charges a capacitor, which is responsible for maintaining the voltage level at the output while the inductor recharges. If the switching frequency is high enough, neither the inductor nor the capacitor ever fully discharge, and the load at the output always has a greater voltage than the input voltage source.

Reactors in a Power System
A choke, also known as a line choke, is a reactor that is used to limit current to AC or DC drives in the event of short circuits inside the drive. When large short-circuit currents are drawn from the source, the choke starts to build a counter-voltage, and the voltage available to the drive is reduced.

What is Pi Filter?
A Pi filter consists of a shunt capacitor at the input side and it is followed by an L-section filter. The pulsating DC output voltage is filtered first by the capacitor connected at the input side and then by choke coil and then by another shunt capacitor.
Ripple (electrical)
A capacitor input filter (in which the first component is a shunt capacitor) and choke input filter (which has a series choke as the first component) can both reduce ripple, but have opposing effects on voltage and current, and the choice between them depends on the characteristics of the load. ...

Chokes Explained
If, on the other hand, you are selecting a choke for a capacitor input supply (such as the typical Marshall or Fender design), then the requirements are relaxed quite a bit. The purpose of the choke in these type supplies is not for filtering and voltage regulation, but just for filtering the DC supply to the screen grids of the output tubes and the preamp section.
