Abstract
The 12-pulse diode rectifier has been widely used in high power applications. Although the dominant 5th and 7th harmonics of the input current are canceled out, the total harmonic distortion is still well above 5%. Therefore additional filtering is required to meet the pertinent standards. In this paper, several methods that deal with the input current harmonics are reviewed. The fundamentals behind these methods are discussed. By utilizing the concept of virtual resistor, a new approach is proposed in this paper to, not only eliminate the AC input current harmonics, but also eliminate DC output voltage harmonics. Moreover, the energy storage integration is possible with the proposed method. We analyze the control and operation of the proposed method. Simulation and experiment results verify the analysis.
