Assume the energy, E, contained in every pulse is constant. Power is just the time rate of change of the energy flow (energy per unit time). So this leads us to define two different types of power. 1. Definition of peak power: 2. Definition of average power: Rate of energy flow in every pulse. Rate of energy flow averaged over one full
Thus the corresponding expressions for the average value of voltage or current for a half-wave rectifier with pulsating DC is given as: V AVE = 0.318*V MAX. I AVE = 0.318*I MAX. Note that the maximum value, A MAX is that of the input waveform, but we could also use its RMS, or "root mean squared" value to find the equivalent DC output value of a single phase …
