Abstract: A versatile operation of any electronic circuitry depends on the power source supplying the power for its operation. The buck converter is implemented using an integrated circuit(IC), LM317. The constructed buck converter was tested for load and line regulation cited in the datasheets for stability. The test and analysis for the linear buck converter was done using setup. The output measurements indicate that the power supply is functional. The measured output values results of the test circuit. The developed output power supply unit is important in measurements, laboratories and test setup. It is implemented for all general applications that require power supply unit. XL6009 module is a DC to DC BUCK-BOOST converter module that operates at a switching frequency of 400kHz. In such high frequency, it provides smaller sized filter components compared with low frequency switching regulators. An improved SingleStage Buck-Boost inverter is provided, using only three or four power semiconductor switches. The inverter can handle a wide range of dc input voltages and produce a fixed ac output voltage. The inverter is well suited to distributed power generation systems such as photovoltaic and wind power and fuel cells, for standalone or grid connected applications. The inverter has a single charge loop, a positive discharge loop and a negative discharge loop. In this complete design of the converter is carried out. This application report gives details regarding this conversion with examples

Предложена разработка цифрового макета изделия, который представляет собой компонент ЭВМ - импульсный блок питания. Производится анализ предполагаемых компонентов персонального компьютера, которые будут установлены в систему. При необходимости есть возможность выбора с добавлением новых компонентов в системный блок ЭВМ. После определения заданных компонентов ПК производится расчет мощности, которая нужна для получения стабильной работы системы в целом. По произведенным расчетам выполняется 3D-моделирование блока питания с разъемами для подключения материнской платы, видеокарты, а также прочих устройств, в том числе и накопителей информации. В работе исследованы вопросы по применению методов линейного программирования для решения поставленных задач в соответствии с исходными данными, а также подходы по получению 3D-модели источника питания с построенными трассами до разъемов подключения устройств и компонентов персонального компьютера. Кроме того, подготовлено программное обеспечение, в котором визуально представлен процесс построения сборочной модели БП согласно произведенным расчетам We propose the development of a digital model of the product, which is a computer component - a pulsed power supply. We carried out the analysis of the expected components of the personal computer that will be installed in the system. If necessary, there is a choice with the addition of new components to the system unit of the computer. After determining the specified PC components, the power is calculated, which is needed to obtain stable operation of the system as a whole. According to the calculations made, 3D-modeling of the power supply unit with connectors for connecting the motherboard, video card, as well as other devices, including information storage devices, is performed. The paper investigates the issues of using linear programming methods for solving the assigned tasks in accordance with the initial data, as well as approaches to obtaining a 3D model of a power supply with constructed routes to the connectors for connecting devices and components of a personal computer. In addition, we prepared the software, in which the process of building an assembly model of a power supply unit is visually presented according to the calculations
