Abstract (English):
Mobile power units (MPUs) are an important element of ground support for aviation equipment, providing electric starting of engines and power supply for onboard systems. MPUs–5D and MPUs–100, built on the Ural–4320 chassis, are examples of the Soviet and Russian engineering school. An important difference between them lies in the AC voltage automatic control systems (ACVCS): the APA–5D uses magnetic amplifiers, which are typical of the technologies of the 1960s and 1970s, while the APA–100 is equipped with a more modern pulse system based on the Schmitt trigger. In this article, we will compare the principles of operation of these systems, their advantages and disadvantages, and assess their development prospects in the context of modern requirements for reliability, efficiency, and integration with digital technologies.
