在寻找中压直流(MVDC)综合电力系统的最佳结构时，除了考虑效率、生存能力和成本效益的总体目标外，还必须考虑短路保护。对具有合适的保护装置和功率转换组合的建筑进行了比较研究。这也导致了最佳的MVDC母线电压介于15kVdc和20kVdc之间。探索了使用封装的SIC器件的硬件实现，目前正在开发中。固态保护设备固有的运行速度也将在故障隔离中发挥作用，从而降低所有系统组件的应力水平。
The search for the optimum architecture for Medium Voltage DC (MVDC) Integrated Power Systems must take into account the short circuit protection in addition to overarching goals of efficiency, survivability and cost effectiveness. A comparison study is performed for architectures with a suitable combination of protective devices and power conversion. This leads also to an optimum MVDC bus voltage somewhere between 15kVdc and 20kVdc. Hardware implementation using packaged SiC devices, currently under development, is explored. The inherent speed of operation of Solid state protective devices will also play a role in fault isolation, hence reducing stress level on all system components.
