description: The subject of development is an auxiliary converter designed to power consumers of the on-board network and recharge the vehicles low-voltage buffer battery from the traction battery. The purpose of the work is to develop a converter for its own needs by replacing inductive elements and the control board in the base converter. Results. In the course of the work, based on the considered basic converter, a functional diagram of the auxiliary converter was developed, the parameters of the high-frequency power transformer and current doubler chokes were calculated, meeting the requirements of the technical specifications. To check the correctness of the calculations, a computer model was developed and its study was carried out, which showed the compliance of the power part with the calculated parameters and the operability of the converter. Based on the consideration of the basic control board, its main disadvantages and limitations for use in the converter being developed are shown, the requirements for the new control board are formulated, and the board components are calculated and selected. An electrical circuit diagram of the control board has been developed, and a description of the operating algorithm of the developed board, sufficient for programming, is given. Application area. Currently, due to economic and other features in the activities of domestic enterprises and organizations related to the development, modernization and operation of electric vehicles for various purposes, the need for the rapid development of these devices, which most flexibly allows the implementation of equipment from new suppliers in any combinations, is especially acute.
