PFC (Power factor Correction) is an electronic circuit technology to optimize the power factor between the AC power supply and the load. Power factor, as an important index to measure the energy conversion efficiency between the power supply and the load, reflects the loss of the power supply in the transmission process. The core goal of PFC technology is to improve the ratio of active power to apparent power by adjusting the current waveform to make it closer to the sine wave, that is, to improve the power factor, so as to achieve efficient use of energy.
Application
PFC (Power factor Correction) is widely used in many fields, which greatly promotes the improvement of energy efficiency and environmental protection. In the industrial field, PFC circuit is widely used in motor drive, transformer, inverter and other industrial equipment, by improving the energy efficiency of equipment, reduce energy consumption, reduce harmonic pollution of the power grid, enhance the stability of the power grid. In terms of household appliances, PFC technology is also widely used in household appliances such as air conditioners, refrigerators, washing machines, and televisions, effectively improving the energy efficiency level of these devices, reducing the user's electricity bill, and reducing the negative impact on the power grid.
