Current waveforms in transformers and rectifiers

  1. Nov 16, 2008 #1
    I was wondering why the current waveform in a rectifier circuit that uses transformers, is not out of phase with the voltage waveform. Does the transformer not shift the current waveform out of phase with the voltage waveform? Thanks for any help.

    The transformer's phase shift is across the windings, that is, secondary voltage is in phase with primary current. On the secondary side where your rectifier is, voltage and current are in phase.
