| Abstract: | The harmonic wave pollution and the technology of harmonic suppress are introduced and the harmonic wave and reactive power in 3-phase rectifier are analyzed in the paper first,and then the filter mode effecting on PF and THD in 3-phase rectifier and the topology effecting on PF and THD in DC/DC converter are finished.The simulation result state that proper input and output filter can suppress the harmonic wave and improve power factor,and two parallel two IGBT DC/DC converter can suppress the harmonic wave near the switching frequency,and decrease the force in IGBT. |
