LECT 02-B) | Exact Reason for Poor Power Factor in Diode Bridge Rectifiers

⚡🔍 Why is the power factor poor in a diode bridge rectifier—even with a resistive load? This is one of the most misunderstood concepts in power electronics, and in this video, we explain the exact core reason with proper physical reasoning, mathematics, and simulation-based insight. In this lecture, we go beyond the common textbook explanation and clearly show why power factor is not only about phase difference, especially for non-linear circuits like diode bridge rectifiers. 🔍 What you’ll learn in this video: Why resistive load ≠ unity power factor in diode bridge rectifiers What actually happens inside a diode bridge during AC operation Why the input current becomes non-sinusoidal and distorted Difference between displacement power factor and distortion power factor How diode non-linearity is the root cause of poor PF Why adding a DC capacitor makes power factor even worse This video is highly recommended for: Power electronics students EV charger designers Researchers and practicing engineers Anyone confused about PF in rectifiers and SMPS 💡 Key Takeaway: " Power factor is poor in diode bridge rectifiers not because of phase shift, but because of waveform distortion caused by non-linear current conduction". #PowerFactor #DiodeBridgeRectifier #PFC #PowerElectronics #EVChargers #AFEConverter #ACDCConverter #Harmonics #UnityPowerFactor #EngineeringEducation #AshishWanode #ashishwanode
