wa2ise, that's true for half-rectified power supplies, but full rectified power supplies will also have reverse current that largely cancells out the forward current in the neutral, leaving just the harmonics as the difference between the two.
Steve, I believe the half wave rectifiers will give you a current draw only during the positive or negative half of the alternating current. The full wave rectifiers will give a current draw during both halfs of the alternating current.
