Abstract
А high-voltage multicellular power supply with energy transfer through a current loop and current transformers is considered. The power source (static-electricity converter) consists of an inverter that generates a current with a preset magnitude in a current loop, which consists of a cable segment, and current transformers, the primary winding of which is represented by a current loop, as well as controlled rectifier cells. Such a decision makes it possible to provide a reliable isolation level between the input and output circuits of the source with a rather simple design of the device. Owing to the use of the same type of rectifier cells in the structure, one can provide a simple scaling of the source according to the output voltage level, as well as a simple setup and repair of the device. The principle of operation has been considered, and the choice of engineering solutions for the main components of the device has been justified. A system for stabilizing rectifier cell output voltage has been investigated as an automatic control system with pulse-phase control. The frequency characteristics of this system for two modes of energy transfer to the load are obtained, the modes are compared, and the most promising one is determined. A mockup of a 10-kV power supply has been manufactured and tested. The results of testing have confirmed the correctness of the calculations and the efficiency of the proposed approach.
