PMIC-Power Factor Controller or Correction abbreviated as (PFC) integrated circuits (ICs) are components used in electronic circuits to increase the efficiency of components with lower power factors. Power factor is a metric used to determine how efficiently input power is used. Power factor correction (PFC) is intended to enhance power quality by increasing this efficiency. They have capacitors or inductors to offset the inefficiencies of motors and other equipment. Additionally, these integrated circuits (ICs) have some other features, such as some computers and other power supplies, that decrease the amount of reactive power produced by a computer system. In resistance to actual power, reactive power energises the magnetic field.
Why is PMIC- (Power Factor Correction) Important?
The objective of PMIC- (Power Factor Correction) is to as closely match the apparent power value measured in VARs (or volt-amp-reactive) to the actual power you are utilising in Watts as possible. As a result, less current will be required to deliver the same amount of real power.
Advantages of PMIC- Power Factor Correction (PFC):
The following are some key benefits of implementing a (PFC)
Technical Advantages
The technical advantages of (PFC) include increased effectiveness and a decrease in power demand, which results in less strain on the cables and switching equipment, lower consumer costs, and support for a greater load.
Commercial Advantages
The production business acquires fewer investment expenses and suffers fewer system losses. Since there are no fees for the extra reactive power, there are also savings on electricity expenditures. The systems and equipment used in transmission and distribution operations are more efficient and survive longer.
Environmental Advantages
Reduces the discharges of CO2.
Types of PMIC-Power Factor Correction (PFC):
Typically, two types or methods of Power Factor Correction (PFC) are used in power supplies, i.e., the active PFC and the passive PFC.
Active PFC
For power supplies that are greater than 100W, active PFC techniques are preferred. This approach is lighter and less awkward and offers a more effective correction.
Passive PFC
Passive PFC technique is implemented in small power supplies that require about 100W or minus.
Applications of PMIC-Power Factor Correction (PFC):
PMIC-Power Factor Correction integrated circuits are frequently used in the below-listed devices:
- Computers
- Power Supplies of Different Kinds
- Electric Heaters
- Induction Welders
- Equipment that uses electrical motors.
- Industries’ equipment to diminish the reactive power generated by bright and high-lighting areas.
