<p>The present invention relates to a multifunction power convertor. The multifunction power convertor of the invention is consisted of a rectification circuit, a filter circuit connecting with the rectification circuit, a inverter circuit connecting with the filter circuit, a differential mode voltage suppression reactors (LS1 , LS2, LS3) and a filter capacitor group which series connect to the output lines (U, V, W) of the inverter circuit respectively. The character of the present invention lies in that a closed toroidal magnetic core is provided on the output lines (U, V, W) between the differential mode voltage suppression reactor and the filter capacitor group, and the output lines (U, V, W) parallel wind on the closed toroidal magnetic core. The advantages of this invention is that, the high frequency signal is insulated by the closed toroidal magnetic core, and the output of the common mode voltage is depressed, so the waveform of outputting voltage is improved, at the same time, the structure of which is very sample, the cost is reduced greatly, the volume and weight of which is also reduced greatly.</p> |
