Computer Models for Simulation and Control of a Traction Supply System

The paper discusses modelling and simulation of power circuits. Models were used to study energy exchange and develop a control system, in particular for vehicles with regenerative braking capability. SIMULINK models were used in control system design, including the selection of circuit components for feedbacks of switched mode converters. Models of the supply circuit were designed as independent blocks. These blocks can be used both, for AC induction motor drives and DC chopper drives. This structure can be used for the behavioural modelling of supply for switched-mode voltage-source traction converters.
