Abstract
The design and development of DC-DC converter circuits are important for increasing and decreasing the direct current energy sources at operating the loads and systems. In this study, a multi DC-DC converter structure is described. The purpose of creating this circuit structure is to create a more effective circuit by offering a different circuit structure. For the proposed DC-DC converter, a circuit structure with five switches is created. This circuit structure is described by mathematical models according to the operation of the four parts PWMs in different time periods. After the mathematical analysis of the circuit structure, the proposed circuit and conventional circuit are operated in the Matlab Simulink. The obtained results are compared. According to the comparisons, the proposed circuit produces a higher output voltage than the traditional one and has a higher performance. Additionally, the circuit is operated for values of different loads using different switching times. Finally, voltages and currents are observed on loads.

Summary
DC-DC converters are needed for many electrical devices used in the industry and social life. The proposed circuit structure with its output voltage multiplexing capability offers superior hardware and a different mathematical model than the conventional converters [10,11,12]. Since it has a simpler structure than other cascade converters, it contains fewer circuit elements [1317]. At the end of the total cycle, the output voltage for the second stage multiplies the output voltage from the conventional DC-DC converter in the first stage This circuit structure is described in the second section with a mathematical analysis. The results show that the proposed circuit is superior to other DC-DC converters
