Feasibility design and experimental research of wireless current charging unit with high efficiency by photovoltaic energy for superconducting hyperloop train

초록

The vacuum tube of the hyperloop train, which is supported by flexible photovoltaic device with low-pressure system, is a proposed high-speed transportation since the electric power of the capsule-type train should be supplied by outsider of vacuum tube. As the high speed hyperloop train should be practically required to supply electric power without overhead wire power lines of pantographs, the research for various wireless power charging (WPC) units has been promisingly required. The necessity of applications for the solar energy has been increased in the industries to improve the operating efficiency. From these reasons, as an advanced approach, authors adopted the photovoltaic (PV) energy as a power source for superconducting levitation magnet. In this paper, authors present the feasibility design and operating characteristics of wireless charging system combined with photovoltaic energy (WCSPE) system for high-speed hyperloop train. Based on the theoretical calculation and experimental performance, the operating characteristics of transferred voltage and current waves, as well as thermal distributions under resonance coupling coils are investigated, respectively, using 250 W of 370 kHz RF generator.
