Research and design papers on (универсальный блок питания) typically focus on "universal" input capabilities (handling both AC and DC), wide-range adjustable outputs, or multi-port modular designs for specialized testing. Key Research Papers and Academic Designs
A comprehensive study of a "universal converter" capable of performing all power conversion types— AC-DC (rectifier) , DC-AC (inverter) , DC-DC , and AC-AC operations in a single architecture. universalnyj blok pitanija shema
A paper from IEEE discusses a portable, multiple-output supply using synchronous Buck and Buck-Boost topologies to provide 3.3V, 5V, 12V, and -12V simultaneously. Common Circuit Schematics (Shema) wide-range adjustable outputs
Research from CyberLeninka explores the development of a high-power universal laboratory power supply designed for marine conditions, focusing on reliability and a wide range of adjustable parameters. and -12V simultaneously.
This paper details the design of a supply that operates with either AC or DC input using a flyback topology and the TOP258PG controller chip to reduce component count.
A conference paper presented in 2022 describes a modular universal ground power supply used for spacecraft testing, allowing flexible selection of distribution paths for complex test requirements.
