Single Phase Current-Source Active Rectifier: design, simulation and practical problems

This research has been motivated by industrial demand for single phase current-source active rectifier dedicated for reconstruction of older types of dc machine locomotives. This paper presents converter design and simulations. The proposed converter control is based on the mathematical model and due to possible interaction with railway signalling and required low switching frequency employs synchronous PWM. The simulation results are verified by experimental tests performed on designed laboratory prototype of power of 7 kVA.
