description: The topic of the work is âCooling system of a powerful voltage converter.â The purpose of the work is to develop a board that allows the use of a temperature sensor built into the housing of the transistor module to increase the accuracy of measuring the temperature of semiconductor crystals of transistor modules of a traction electric drive, with subsequent transmission via a serial communication channel with the RS-485 interface of data on the temperature of the crystals of transistor modules to the traction converter control board. Results. In the course of the work, based on the considered basic converter, the concept of using a transistor thermal sensor module built into the housing was developed, the issues of constructing cooling systems were considered, the maximum temperature of the cooler was calculated, the heat release by the transistor module was simulated, and a functional diagram for connecting thermal sensor boards was developed. Based on the consideration of the basic cooling system, its main disadvantages and limitations for use in the converter being developed were determined, and the components of the developed board were calculated and selected. An electrical circuit diagram of the temperature control board has been developed. Application area. Increasing the density of components, which leads to a reduction in the overall characteristics of converters, is an urgent task not only for transport, but also for stationary installations. The work has an applied focus; the results obtained can, with appropriate adaptation, be used in the construction of other converters.
