Current control in three-phase switching converters and AC electrical machines

Proceedings of IECON'94 - 20th Annual Conference of IEEE Industrial Electronics, 2002
In this paper, the design of current control loop and selection of the switching logic for PWM three-phase switching power converters (inverters and rectifiers) and AC electrical machines are presented. The approach is based on the deliberate introduction of the sliding mode motion in the control system.

Comparative analysis of prospective high-voltage direct current converters of electric locomotive

2013 14th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices, 2013
Two types of DC-DC converters are compared. These converters are constructed on the basis of a single-phase bridge and a single-phase half-bridge of cells' circuits in the multichannel system. Each channel contains a single-phase VSI, a high-frequency transformer, an active single-phase rectifier on the basis of a turned VSI.
