Reliability analysis of a developed stabilized direct current pulsed power supply for aircraft electrical systems

This article presents a methodological approach to electronic device design from the perspective of reliability assurance. The paper provides mathematical and structural models using as an example a developed pulsed power supply that converts three-phase alternating current into regulated DC voltage. The reliability analysis yielded theoretical performance metrics, including the mean time between critical failures (MTBCF). Furthermore, it demonstrates why designing reliable pulsed power supplies represents not only a technical challenge but also a complex process requiring in-depth circuit design knowledge, meticulous calculations, and rigorous component selection methodology.
