Following the scarcity of non-renewable resources such as oil, gas and coal, more research is focused on the issue of high energy consumption and society's dependence on fossil fuels. The use of renewable energy and the development of microgrids can be necessary to reduce dependence on fossil fuels. Photovoltaic systems play a key role in microgrids as a source of renewable energy supply. In these systems, the output voltage of the cell is usually much lower than the voltage required by the DC bus, and as the output current increases, the amount of this voltage decreases significantly. Therefore, the presence of a step-up DC-DC converter with a wide input voltage range is necessary to connect the low-voltage cell source and the high-voltage DC bus connected to the inverter. In this paper, a new structure is presented for non-insulated DC-DC boost converters based on voltage lift technique. The proposed converter has a proper voltage gain at output and an acceptable voltage stress on switch and diodes in comparison with recent references. The proposed converter has a switch with easier control and high reliability due to the input source common point and the output load of the converter. Analysis of the voltage stress as well as selection of suitable elements along with converter analysis in continuous mode are performed and calculation validity is confirmed by presented laboratory results.

Iranian literature is one of the hallmarks of Iran's long-standing civilization that embodies the customs and art of this land. The play is also a literary genre that has long been prevalent in the culture of this land and has remained in the form of mourning, surrealism, glorifying dances, painting, similitude and ta'ziyeh and more. Ancient Persian literature cannot be regarded as a stand-alone literature, but since ancient Persian literature and art have the same source, It can be said that the writings of the Iranian artist's literatures have been marked by the art of the show, and the dramatic literature has long been synonymous with other arts such as music and painting alongside literature. Persian literature is illustrative and meaningful and encourages the audience to visualize the text in order to get better And it is from this that an artistic interaction is formed between the writer and the reader, and by the act of reading and performing them, the dramatic capacity of the works is manifested. There is no doubt that ancient literature is the basis for the "representation of species" which can be seen in many works such as the works of the military, Attar, Rumi, Ferdowsi, Beihaqi, oufi, Tasuji and others. Since the play is the home of world media and one of the best known ways of enriching Iranian literature; The present study seeks to examine the dramatic capabilities of such works that remain anonymous and a powerful tool for the representation of Iranian history, art, culture and thought And express the place of these works in the field of theatrical literature.

The poetry of the Islamic Revolution is a continuation of the previous Persian poetry and encompasses all the territories of the past, both in terms of themes and themes and in terms of form. The poetry of the Islamic Revolution has both an epic theme, a mystical, a romantic, a religious, a social and a political one; it is better to say that there are no divine, humane and universal themes that the poets of the revolution have not addressed. Romantic poetry is one of the branches of revolutionary poetry that has a remarkable presence in the poetry of this period.The romantic lyrical songs of the revolution, which are sung in all forms, especially the sonnets, are mainly of poetic dignity and decency, which in this respect are distinct from the pre-revolutionary lyrical poems. Since love and the expression of pure emotions and emotions in the form of the most beautiful descriptive sentences in the literature of the revolution is a part of the themes which we consider to be rich literature, In the present study, we have examined the richness of post-revolutionary literature by using descriptive and content analysis methods. Considering the morale of the people as well as the poets of the poets at this time, it can be said that rich literature, besides the mystical and epic themes, has a considerable part of the literature of this period.
