Abstract: In this paper we treat the case where unbalance is on the level of the power supply, and present a method to compensate this unbalance of the network. This method is based on considering a general three phase voltages of unequal amplitude and arbitrary phase. This voltage system is then composed in two sequences: positive and negative sequence. The zero sequence is assured to be zero. For each sequence, a modulation switching function is determined. The voltage in the dc side is then expressed as a function of two sequences voltage, and the related switching. In the above DC voltage expression, there are terms that generate harmonics, we make choice that the sum of harmonic terms equals zero. A global switching function is then determined
