description: The subject of development was a converter control device designed to convert the traction network DC voltage of 600 V into a DC voltage of 28 V, suitable for powering on-board network consumers, as well as for recharging a buffer battery. The purpose of the work is to develop a control board for a switching DC voltage stabilizer - a DC / DC converter used to power on-board consumers of urban electric transport, as well as recharging its buffer battery. The main difference between the developed board and the considered functional analogue is the fully digital control of power transistors, in addition, in addition to the existing ones, a modern CAN interface, which is widely implemented in passenger transport, has been added. The theme of the work is âConverter of direct voltageâ. Results. Description of the converter of own needs. Formulation of requirements for the developed control board. Calculation and selection of components. Development of an electrical circuit diagram of the control board. Description of the operation algorithm. Application area. When designing devices and circuits for new and modernized rolling stock, it is necessary to develop a new circuitry and algorithmic base for devices. At present, due to economic and other peculiarities in the activities of domestic enterprises and organizations associated with the development, modernization and operation of tram cars and trolleybuses, the need for the rapid development of these devices is especially acute, which most flexibly allows the introduction of equipment from all new suppliers in any combination. Static converters are no exception, requiring a revision of the methods of their implementation and software processing. Work conclusions. The chosen approach will reduce the number of components used, at least, thereby increasing reliability, as well as more flexible use of the developed board in other projects similar in functionality. The work has an applied focus, the results obtained can be applied with appropriate adaptation in the construction of other DC / DC converters. The design approach shown can also be extended to a wide range of equipment, regardless of its purpose, if the existing system is replaced with a solution using a modern microcontroller.
