A method of electrical balancing in a three-phase system is disclosed. The steps are: obtaining the magnitude and phase of each line-to-neutral output voltage; aligning a first line-to-neutral voltage with the real axis; choosing two voltages and adding a third voltage complex conjugate of the greater of the two previous voltages; calculating the positive sequence, the negative sequence and the zero sequence; cancelling the negative sequence; calculating the positive sequence and zero sequence of the new line-to-neutral voltage system; adding positive sequence voltage and zero sequence voltage to the positive sequence and zero sequence; calculating the new line-to-neutral voltages from the new positive sequence voltage and the new zero sequence voltage, with negative sequence voltage equal to zero; repeating the two previous steps until the module of the new third line-to-neutral voltage is equal to the module of the line-to-neutral output voltage discarded in the third step.
