The PFC (Power Factor Correction) transformer in the power supply mainly plays the following roles:

Improve power factor:

PFC transformers effectively improve power factor by adjusting the input current of the power supply to keep it synchronized with the input voltage. Power factor is an important indicator for measuring power efficiency, which reflects the energy utilization of the power supply during transmission. Improving the power factor can reduce energy loss during the conversion process and enhance the overall efficiency of the power supply.

Reduce harmonic pollution in the power grid:

Traditional rectifier circuits generate a large amount of harmonic currents, which can cause pollution to the power grid and affect its stability and reliability. PFC transformers adjust the current waveform to synchronize with the voltage waveform, thereby reducing the harmonic components of the current and minimizing harmonic pollution to the power grid.

Reduce equipment costs:

PFC transformers can reduce the volume and weight of power supplies, which helps to lower the manufacturing cost of equipment. In addition, due to the improved power factor, the energy required for the power supply to operate is reduced, thereby reducing the operating cost of the equipment.

Meet regulatory requirements:

Many countries and regions have clear regulatory requirements for the PFC performance of power sources to ensure the stability and reliability of the power grid. The use of PFC transformers can meet these regulatory requirements and ensure that power products comply with relevant standards and regulations.

Improving the quality of the power grid:

PFC transformers help improve the overall quality of the power grid by increasing power factor and reducing harmonic pollution. This can improve the stability and reliability of the power grid, and reduce the risk of power grid failures.

conserve energy ,reduce emissions:

Due to the improved power factor and reduced energy waste caused by PFC transformers, it contributes to achieving energy-saving and emission reduction goals. This is of great significance for environmental protection and sustainable development.

In summary, PFC transformers in power supplies play an important role in improving power factor, reducing grid harmonic pollution, lowering equipment costs, meeting regulatory requirements, improving grid quality, and energy conservation and emission reduction.
