6 FAQs about [The role of pfc energy storage inductor]

Why is a PFC inductor coiled?

The coiled structure helps to create a magnetic field inside it based on Ampere’s law. A PFC inductor is nothing but an ordinary inductor attached in a circuit for the purpose of adjusting the power factor value to obtain high efficiency and proper power transfer. So the working principle of PFC inductor is the same as the ordinary inductor.

What are the benefits of a PFC converter?

While the primary benefit of a PFC converter is a high power factor and low THD, there are secondary benefits that the overall AC/DC power supply enjoys due to the inclusion of active PFC. Due to the high output voltage of the PFC stage, a moderate amount of energy can be stored in the PFC output capacitance.

How does active PFC work?

Active PFC uses semiconductor switches and energy storage elements (again, inductors and/or capacitors) to shape input current so that it tracks input voltage while (usually) delivering a semi-regulated output voltage.

What are inductors used for?

Inductors are crucial components in electrical systems, serving to store energy within a magnetic field when current flows through them. These components are common in electronic circuits, power supplies, and applications that require filtering, energy storage, or impedance control.

Which PFC is used for low-capacity power supplies?
