The power system comprises the AC input distribution, rectification, DC output distribution, and monitoring system. The four parts are in turn made up of different components as shown below:
1AC input distribution: AC distribution cabinets.
2Rectification: red insulation diodes.
3DC output distribution: diodectifiers an chain, insulation status detector, switching branches (connected to the switching bus), and control branches (connected to the control bus).
4Monitoring system: power control unit (PCU) and power distribution monitoring box.
