A system for converting a time-varying periodic, complex electrical input wave to DC with reduced response to selected harmonic distortion components of the wave, the system including a conventional AC-DC converter and means for selectively altering the gain of the converter between predetermined phase angles with respect to the fundamental of the wave. Gain alteration is typically effected by a second AC-DC converter having a different characteristic sensitivity to the distortion components than the first converter. The outputs of the two converters are scaled and then summed, the scaling factors being dependent on the harmonics the effect of which is intended to be reduced. One converter is an average-sensing device, the other being a peak-To-peak or peak-averaging sensing device.
