| Abstract: | This paper has studied a new type of Pulse Width Modulation （PWM） rectifier that has the function of harmonic suppression and reactive power compensation. The extraction method of the reference harmonic and reactive current and the voltage regulation method are discussed in detail. A detection method based on instantaneous reactive power ip-iq theory is adopted to give the harmonic and reactive reference currents respectively. In order to compensate both the harmonic and reactive power currents effectively, a voltage-current and dual closed-loop controlling method are presented,in which a kind of fuzzy PI hybrid control is used to the DC bus voltage regulator. At last, simulations based on the PSIM software prove that the method has good voltage regulation performance and compensation effect for harmonic and reactive currents under the different work modes. |
