“…As an example from HVDC systems, the active and reactive power in VSC‐based HVDC systems can be controlled independently and rapidly [53], which enables VCS‐based HVDC to integrate weak and passive networks to the system [49]. In addition, the VSCs inherently have faster dynamic response [54]. Among VSCs, however, AACs have limitations in independent active and reactive power control, as discussed before.…”

Medium‐voltage DC (MVDC) electric railway systems have several advantages over conventional DC and AC railway electrification systems. These advantages include higher capacity, possibility of connecting to power networks at lower voltage, removal of neutral sections, smaller line voltage drops, and longer distances between traction power substations. This paper reviews in depth the arrangements for MVDC railway electrification systems proposed in the technical literature and the topologies used for high‐power medium‐voltage AC‐DC converters. With reference to typical requirements of a MVDC railway electrification system, the pros and cons of the topologies are critically analysed. Moreover, this paper reviews the DC‐DC power converter topologies for on‐board power electronic traction transformers, required to interface the MVDC power supply with the traction motors. Finally, the review highlights the existing challenges of MVDC electric railway systems and the potential areas of future research.

“…In addition, the application of current source converters has gradually appeared in applications that were originally suitable for voltage source converters. For example, the following six articles respectively applied current source converters to micro-grid [12], wind turbine [13], multilevel converter [14], energy management in traction applications [15], indirect matrix converter [16] and permanent magnet synchronous motor drive [17]. It can be seen that the current source type converter has characteristics that make the control method and application research more and more in-depth and extensive.…”

Aiming at the function and technical requirements of high-power photovoltaic cell simulation, high-performance programmable logic power supply and dc motor simulation, a high frequency isolation hybrid topology and control strategy based on current-source/voltage-source converter was studied and proposed. Firstly, according to the performance requirements of photovoltaic cell analog power supply, the control strategy requirements of the high-precision wide-range hybrid topology were proposed. Secondly, the working principle of the new hybrid topology was analyzed. At the same time, the equivalent model of the new hybrid topology was simplified and established, and the overall control strategy of the hybrid topology based on current compensation and sliding mode variable structure was proposed. Finally, simulation and experimental research on the hybrid topology was carried out, and the experimental test of photovoltaic cell simulation was completed. The simulation and experimental results show that the hybrid topology and control strategy proposed in this paper has the characteristics of wide-range output regulation, fast dynamic response, high efficiency and high power factor, and can be used for high performance photovoltaic cell simulation, programmable logic power supply and DC motor simulation.
