| Abstract: | This paper presents a new method to calculate the harmonic currents on both DC and AC sides in a three phase bridge rectifier operating under pre existing voltage distortion The proposed method,which takes into account the AC side reactances and harmonic voltages already existing in AC network,gives out the calculating equations of DC and AC sides harmonic currents Some practical rectifier circuits are calculated and carefully tested The calculated results show that the proposed method is more accurate and more practical |
