In this paper, a new nonisolated dc-dc converter based on series connection of several number of diode-inductor basic units with high voltage gain and low voltage stress on power switches is proposed. These diode-inductor basic units (D-L) recieve energy from input source in the time interval of turning on the switch and by delivering it to the voltage multiplier cells in the time interval of turning off the switch lead to increase voltage gain. Therefore, the converter is able to generate high voltage gain in low duty cycle. The proposed converter consists of higher voltage gain and lower voltage stress on power switches in comparison with the conventional converters. In addition, this converter includes of simple control system because there is only one power switch in it. In this paper, the operating of the proposed converter in three different modes of continuous conduction mode (CCM), discontinuous conduction mode (DCM) and boundary conduction mode (BCM) are investigated. Moreover, a methode to design the nominal voltage and current values of used elements are presented. Finally, the accuracy performance of the proposed converter is verified thruogh simulation results in PSCAD/EMTDC software program.read more

Cascade Cockcroft–Walton Voltage Multiplier Applied to Transformerless High Step-Up DC–DC Converter
TL;DR: In this paper, the proposed control strategy employs two independent frequencies, one of which operates at high frequency to minimize the size of the inductor while the other one operates at relatively low frequency according to the desired output voltage ripple.
