This paper introduces a dual-switchhigh step-up DC-DC power converter. The proposed converter features high voltage gain, relatively low cumulative stored energy over its inductors, stress on the active switches, and efficiency, even at duty ratio. An assessment of against conventional boost is presented in terms steady-state time, efficiency. shows reduction 81.25% 62.5% inductors to comply wi...

A current-fed LLC resonant converter is proposed for high-voltage and high-power applications. Here, a two-phase interleaved structure used in the input stage under continuous conduction mode (CCM) to effectively reduce current output voltage ripple values filter capacitors volumes. Due expandable high gain, configuration suitable applications since low stresses are applied across its component...

In this article, an ultra-high step-up DC-DC converter has been proposed. The topology of the is a combination cascaded boost converter, positive output super lift Luo (POS LLC), and voltage multiplier cell (VMC). lower values duty cycle provide more than 10 times gain. Consequently, high gain provided beside value voltage/current stress semiconductor acceptable efficiency. With detailed look, ...

In this article, a nonisolated three-port dc-dc converter with high voltage conversion ratio is proposed. the proposed converter, by changing place of input source between each three ports, different single-input two-output operation modes are achieved. The current ripple eliminated at low side for whole range duty cycles. ratios can be increased increasing turns second winding coupled inductor...

In this paper, a novel high step-up DC-DC converter with coupled-inductor and voltage-doubler circuits is proposed. The converter achieves high step-up voltage gain with appropriate duty ratio and low voltage stress on the power switches. Also, the energy stored in the leakage inductor of the coupled inductor can be recycled to the output. The operating principles and the steady-state analyses ...
