Abstract
BACKGROUND: The development of electronic components and, consequently, high-frequency digital pulse converters requires the improvement of existing interstate standards for the correct assessment of the performance and reliability of advanced devices.
AIM: This work aimed to review the existing and to develop and validate the new requirements and control methods in accordance with GOST 33726-2016: Static Non-Tractive Converters for Railway Rolling Stock. General Specifications in order to improve the reliability and quality of performance assessment of advanced pulse voltage converters included in a single-phase on-board power network.
METHODS: Structural analysis methods and field testing of a high-frequency converter prototype were used. The study is based on the interstate standard, mathematical modeling, and field experiments.
RESULTS: The findings confirm the need for additional measurements of the converter’s performance in idle mode and with a reactive load; mandatory galvanic isolation requirements for battery-powered converters; modification of the monitoring methods for the total voltage harmonic distortion, and other.
CONCLUSION: The findings will allow for more detailed regulation of the converter certification process and methods to ultimately improve the reliability of the devices.
