“…Nowadays, the research mainly focuses on how to enhance the system capacity. A multi-level cascade converter has the advantages of larger capacity and simpler control technique [8][9][10], therefore, multi-level cascade converters can be applied to this system. Consequently, in practical applications clamped multi-level converters mainly consist of three-level and five-level converters.…”

Abstract:The advanced traction power supply system (ATPSS) is a new directional development for traction power supply systems, which can totally remove the neutral sections and effectively promote power quality. However, the existing converters suffer from small substation capacity. In this paper, a new configuration based on a three-level neutral point clamped (3L-NPC) three-phase to single-phase cascade converter in a substation is proposed for ATPSS, which can be used to match the capacity of the converter for high voltage and large power applications. The control strategy of the proposed converter is analyzed in depth, and the phase disposition sinusoidal pulse width modulation (PD-SPWM) with phase shift carrier SPWM (PSC-SPWM) is employed in the inverters. Then, the inductance equalizing circuit is applied for the voltage balance on the DC-link. Besides, a LC filter circuit is designed to eliminate the double line-frequency ripple of DC voltage. Afterwards, a simulation model and an experimental prototype are developed, respectively. The simulation results show that the proposed converter in this paper can not only meet the requirements of voltage and capacity for the traction network, but also improve power quality. Finally, the experimental results verify the correctness and feasibility of the proposed control strategy. OPEN ACCESSEnergies 2015, 8 9916

“…The system is based on power electronic compensation device-Active Power Compensator (APC), which solves the existing electrified railway power quality problems, achieves co-phase power supply in substation and halves the number of neutral sections. In [4], the ATPSS based on multi-level three-phase to single-phase converter is proposed, of which the system structure is shown in Fig. 1 (c).…”

As an ideal power supply, the advanced traction power supply system (ATPSS) is approved to totally remove the neutral sections and promote the power quality, which is a new direction development for traction power supply system. The existing ATPSS based on three-phase to single-phase converter needs to match the step-up transformer. The output current of this system is so heavy that it requires parallel structure to share current, which makes high requirements for manufacturing facilities. What's more, circulation suppression in the parallel system must be taken into consideration. In this paper, a new ATPSS based on a three-phase to single-phase cascaded converter without output transformer is been studied. The structure of three-phase to single-phase converter and its control system are deeply analyzed. Then the cascade structure implementation of the converter is studied. Finally, a simulation model for this system is built. The simulation results show that the new system built in this paper can remove the output transformer, not only meets the voltage of the traction network and capacity requirements, but also improves power quality. The results verify the correctness and feasibility of main circuit structure and control strategy.
