In this episode of Electronics Basics, we will be having a closer look at Power Factor Correction Circuits aka PFCs. It sounds like a boring topic but it is super important for the electrical future of our power grid. Along the way we will find out about current waveforms, phase shifts, current harmonics and what passive and active PFCs are and can do. Let's get started!
