I know how to find the Vdc and Vrms for a certain signal and in my case, the full wave rectified pulsating dc signal. I know its rms value (Vrms = 0.707 Vp) and its average value too (i.e. Vdc = 2Vp / 3.142)
But I am confused about which one will dictate the charging voltage to be given to the battery ? In other words, I want to ask is it the Average Value (Vdc) of the waveform that charges the battery or is the the RMS Value (Vrms) that charges it ? If I simplify more, I would ask that if I need to charge the battery to 13.2 volts through a fully rectified pulsating signal, should I set its RMS value to 13.2 volts or should I set the Average value to 13.2 volts ?
