And the traditional passive filter's function is also limited for avoiding the resonance and harmonic enlarging. The auto-compensator and harmonics shielding converter transformer can be used to solve these problems, which is based on the principle of the winding ampere and turn's balance. This paper elaborates this kind of transformer filter mechanism. In the view of the HVDC system, a new winding connection plan is proposed, and the filter optimization model is created.
