Design of a DC power supply with power factor corrector by Taguchi method

The aim of this paper is to develop a study of Taguchi optimization method for a switching mode DC power supply with power factor corrector (PFC). Power factor and efficiency are the basic indicators for both of power quality and power saving. To attain these two factors in switching mode power supply design is the goal for power engineers. The most effects are the setting of initial parameters. Orthogonal arrays of Taguchi and the signal-to-noise (S/N) ratio are employed to find the optimal levels and to analyze the effect of the parameters for DC-DC converter with PFC. Confirmation tests with optimal levels are carried out in order to illustrate the effectiveness of Taguchi optimization method.
