PFC (Power Factor Correction) is an important mechanism used in power electronics to improve the performance and overall effectiveness of electrical systems. PFC uses a variety of techniques to improve the power factor coefficient of electric circuits. As a result, energy is used more efficiently, and less waste is produced. Recognising the role of PFC is the most important factor in the smooth operation and durability of electrical infrastructure. In this blog, we will explain what power factor correction is in electrical engineering and why it is essential.
