Designing a Multi-input Single-output DC-DC Converter (MISO) for Use in Low-power Applications

Today, with the development of renewable sources, their use in the network has also increased. The important point is the power of these sources, which have a relatively low output power, so in industrial applications, it is necessary to design converters to allow the combination of these sources at the input and in the Create a high voltage and power output for the user. The purpose of this article is to design a multi-input and single-output DC-DC converter with high efficiency. The proposed converter can amplify various input source voltages by combining them to obtain a stable dc output voltage for the load demand. Based on different situations, the proposed converter operating mode, the input power supplies are connected in series and added to the converter with the designed pulse width. Modulation can greatly reduce the conduction losses of switches. The results showed that the proposed high-efficiency DC-DC converter with dual power supply greatly reduces conduction and switching losses in the system. This topology was developed to overcome the disadvantages of large size, complex topology and high cost in conventional converters with single-input power supply mode. MATLAB simulation software has been used to evaluate the design.
