Technical Electrodynamics| Резюме: | High-speed train is supplied by alternating current (AC) power and bases on single-phase four quadrant (4Q) converter as one necessary part of the AC-DC-AC transform process. This paper introduce hysteresis control system of 4Q-converter and it’s regulating characteristics. Regulating characteristics are obtained on the basis of energy balance equation and describes dependence of output voltage and regulating coefficient of the hysteresis control system ξ in rectifier-mode and recuperation-mode. The nonlinear character of the control characteristic and its dependence on the load current is determined. It is concluded that for a steady process of rectification and recovery, the automatic control system must contain a feedback channel of the load current. A 4QS-converter model was developed in the Matlab simulation environment where the theoretical positions of output voltage regulation and high power quality parameters in rectification and recovery modes were confirmed.
