Input LC Filter Design of Diode Rectifiers Considering Filter VA Rating Reduction |
| Abstract |
In this paper, input LC filter design of diode rectifiers considering filter VA rating reduction has been propoesd. It consisted of an input LC parallel resonent tank whose inductor and capacitor values are selected so that the input filter presents an infinite impedance to harmonic input ac current component. The operation of proposed input filter has been analyzed in detail under steady state conditions. Performance evaluation and related design data have been provided on Per Unit basis for the proper implementation of diode rectification system. Finally, Detailed input and output current analysis has shown that the proposed input filter yield high quality input ac current waveforms, in particular, high input power factor values and more reliabilty which reducing the VA rating of passive components as compared to the standard type LC filter. |
