This article describes the constitution for the New High-Power Filter and Rectifier System (NHPFRS). The principle to reduce the harmonic flux of its rectifier transformer is analyzed. According to the measured data, the model of the NHPFRS for the engineering prototype is established. Using ANSYS finite element analysis software, a three-dimensional model of the field-circuit coupled for the new rectifier transformer is built. The transformer tank harmonic flux and harmonic eddy los- ses are calculated under the three conditions. The results validate that the NHPFRS has a few of features such as small harmonic flux and small harmonic losses.
