Power Factor Correction (PFC) is a technique used to improve the power factor of a power supply or electrical system. The power factor is the ratio of the real power (active power) to the apparent power (vector sum of real and reactive power). *Why is Power Factor Correction important?* 1. *Improved efficiency*: PFC helps reduce energy losses and heat generation in the system. 2. *Reduced current*: By improving the power factor, the current drawn from the mains is reduced, which can help reduce
