چکیده :

This research aims to construct a high-voltage boost DC-DC ‎‎converter using the interleaved technique with coupled inductors ‎‎and voltage multiplier cells such as switch capacitors. The ‎‎presence of capacitors increases the voltage gain, which leads to a ‎decrease in the switches' voltage stress. The voltage of the ‎‎switches is significantly lower than the output voltage. It makes it ‎‎possible to use MOSFET switches with a lower voltage rate, ‎‎which, in addition to cost reduction, leads to decreased ‎‎conduction losses. Also, due to the presence of coupled ‎inductors, ‎‎the decreasing current of the diodes is controlled through leakage ‎inductances. In this case, ‎zero-current switching is established ‎when the diodes are turned ‎off, which increases efficiency. In this ‎article, The stability of the ‎suggested converter has been assessed ‎and verified. Also, this converter has the feature of a symmetrical ‎input current and common ground between input and output. ‎With an ‎input of 20V and a voltage gain of 26.6, the output ‎voltage is ‎533V, resulting in a power of 320W. Moreover, the ‎calculated equations are proven through simulation.‎
