L. Hsiu et al. [34] at low output ripple and noise in voltage and current and for this design a model of coupled inductor and transformers on a common core is use that provide Zero-voltage– switched Dual–SEPIC converter with coupled inductor. H. F. Bilgin et al. [35] gave a design criteria, operating feature and characteristic of the buck type PWM rectifier employed in a unity PF dc motor drive. As per this paper single–stage UPF buck –type PWM uses For-low harmonic distortion in Ac supply current and nearly UPF over a wide operating shaft speed Range. And these output voltage and current in limit avoid any type of failure risk in current connection even for oldest motor design, aging in insulation, mechanical failure due to circulation …show more content…

Mokhtar Ali et al. [41] gave new technique which allows the use of lower voltage Rated Semiconductor .This improves the performance of the system. This technique use SEPIC as the practical driver. L.K. Wong et al. [42] gave that Conventional method like averaging and small signal linearization are enough and powerful for basic converts like buck and boost but for high order like SEPIC these are not sufficient so the Meson’s gain formula and signal flow graph help the manipulation. Mohammad Mahdavi et al. [43] introduced a new PFC converter that have reduced no of component that subsequently reduces conduction losses. This proposed converter is operating in discontinuous conduction mode and having only voltage control loop i.e. no current loop is required whereas conventional arrangement have Booth loop controls and also operates in continuous conduction Mode. M.S. Song et al. [44] gave that by providing a direct new way between input and output by using some Auxiliary diodes and switches in addition to the SEPIC converter provided a highly efficient step up and step down converter in continuous mode. Ashish Shrivastava et al. [45] gave PFC based LED driver for power factor correction in the ac system. This topology consists PFC SEPIC converter which is operating to drive LED lamp in the continuous conduction mode. In this
