The present invention relates to a power converter with low common mode noise, at least comprising: a ground terminal, a power converting unit, a capacitor unit of common DC bus, a filtering capacitor unit, a filtering inductor unit, and a compensation unit. In the present invention, a filtering inductor unit including three primary windings and three auxiliary windings is used for making the power converting unit couple to three phase terminals of an external electrical apparatus. Moreover, the three auxiliary windings are further formed a compensation circuit by way of being connected with the compensation unit, such that the engineer is able to easily and effectively suppress the common mode noise occurring near the resonant frequency of the power converting apparatus through selecting a suitable turns ratio of the primary windings and the auxiliary windings.
