General determination of rank and peak value of primary current harmonics in any 3-phase rectifier network

In a rectifier network, or group of such networks, fed by a 3-phase power supply, if the pulse number p of the rectified voltage is equal to 3 (or a multiple of 3), the primary currents have kp±1-rank harmonics only, k being an integer. In this paper, a general demonstration of this property is given, regardless of whether the load is infinitely inductive or not, and without ever specifying the diagram used. This demonstration gives an expression of the peak value of harmonics that makes them much easier to calculate when the rectified current undulation is not neglected.
