The article considers the position of vibroacoustic diagnostics of rolling bearings of electric rolling stock. The developed algorithm for determining the condition of bearings indiscriminately, diagnosing during the current repair of TR1 at a specially designed position, the structure of the power supply (PS) and its parameters are determined in accordance with the intended diagnosis of bearing units of DC suburban electric trains, the functional diagram of the power supply, a simplified diagram, a diagram explaining the principle of operation and the required filling factor of the pulse voltage regulator is determined.
