Analysis of the third-harmonic current injection method presented so far indicates that the method can significantly improve total harmonic distortion (THD) of the input currents of three-phase diode bridge rectifiers. In Chapter 5, optimization of the injected current amplitude and phase is performed, and it is shown that for the minimum of the input current THD the injected current iY supplied to the current injection device should be in phase with the spectral component of the diode bridge output terminal voltages at the triple of the line frequency, with the amplitude equal to 3 2 of the output current. This requires a power to be taken by the current injection network from the diode bridge output terminals in order to provide the optimal third-harmonic current injection. This power is shown in Chapter 5 to be equal to 8.57% of the rectifier input power.
