Direct single-stage power converter with power factor improvement for switched mode power supply. p. 468-476 This paperpresents a direct single-stage power converter using single-phase isolated fullbridge converter modules, with inherent power factor correction (PFC) for a 12 kW switched mode power supply (SMPS). The advantages of the proposed converter are its simple control strategy, reduction in number of conversion stage, low input line current harmonics, and improvemebt in power factor. Analysis of the single-stage converter is carried out in continuous conduction mode operation. Staedy state analysis of the proposed converter in conducted to obtain converter parameters. A systematic design procedure is also presented for a 12k W converter with a design example. The effect of load variation on SMPS is also studied in order to demonstrate the effectiveness of the proposed converter for the complete range of load conditions. A set of power quality indices on input ac mains for an SMPS fed from a single-stage converter is also presented for easy comparison of their performance. Power factor correction (PFC).
