4-6 Figure 4-4A.—Comparison of Epeak to E avgin a half-wave rectifier. Epeak WAVEFORM. The average value of a sine wave is 0 volts. View B of figure 4-4 shows how the average voltage changes when the negative portion of the sine wave is clipped off. Since the wave form swings positive but never negative (past the "zero-volt" reference line), the average voltage is positive. The average voltage (Eavg) is determined by the equation: Where: Eavg  = Epeak × .318   Thus: Eavg = 162.6 × .318 Eavg = 51.7 volts Figure 4-4B.—Comparison of Epeak to E avgin a half-wave rectifier. Epeak WAVEFORM Ripple Frequency The half-wave rectifier gets its name from the fact that it conducts during only half the input cycle. Its output is a series of pulses with a frequency that is the same as the input frequency. Thus when operated from a 60-hertz line, the frequency of the pulses is 60 hertz. This is called RIPPLE FREQUENCY. Q5.   What is the name of the simplest type of rectifier which uses one diode?
