Current in the primary coil of transformers used in rectifier circuits

  1. Feb 26, 2013 #1
    Can anyone please clarify if the current in the primary coil of the transformer follows V(s)I(s)=V(p)I(p) when i am trying to figure out the peak, surge and average current through the primary coil of a transformer in a full wave rectifier.

    Also, if it does, do I just use the peak voltage or the rms value?

    It does and it does not . That depends on what are u trying to calculate.

    You can use this relationship to calculate the "peak" voltage / current and R.M.S value , depending on what you need.

    One more thing, as long as the average current or voltage is concerned it would mathematically be zero since the Current is a sine wave function . The mean value of such a current over one complete cycle would be zero .
