The ripple in the output waveform can be reduced using the filter. • To remove or reduce the ripple from the output waveform, the RC time constant of the filter circuit should be much larger than the time period of the half wave rectifier. • Parameters of the half wave rectifier: • Average Value: Vm / π • RMS Value: Vm/2 • Ripple Factor: 1.21 • Efficiency: 40.6 % • PIV: Vm • The link for the other useful videos related to diode: • 1) Introduction to a diode and V-I characteristics of the diode • • Introduction to Diode: What is Diode ... • 2) The diode resistance Explained: • • Diode Resistance Explained (DC Resist... • 3) RMS and Average Value: • • RMS (Root Mean Square) Value and Aver... • • This video will be helpful to all students of science and engineering in understanding the half wave rectifier. • Follow me on YouTube: • / allaboutelectronics • Follow me on Facebook: • / allaboutelecronics • Follow me on Instagram: • / all_about.electronics • Music Credit: • http://www.bensound.com/ • #HalfWaveRectifier
