A New Non-isolated High Step-up Converter with Low Voltage Stresson the Power Switch and High Efficiency

In this paper, a high step-up quadratic converter ispresented, the conditions of zero current switching to turn on theswitch and zero voltage switching to turn off the switch areprovided. The voltage stress of the converter is very low and allthe diodes are switched off at zero current switching andtherefore do not cause noticeable losses to the circuit. Also, thecircuit does not have an additional switch, so the control of theconverter remains simple as PWM and its implementation issimple. The converter is simulated in PSPICE software and theresults of the analyzes confirm the proposed converter.
