Numerical and experimental analysis of power generation characteristics in beam direction control of optical wireless power transmission with mirror

Advanced Progress of Optical Wireless Technologies for Power Industry: An Overview

“…Furthermore, the OWPT system with multiple mirrors was considered, and the number of mirrors required for rooms of different sizes was studied. In this paper, the beam can be transmitted through the mirror to a device far away from the light source and with a small inclination angle, which avoids the energy waste caused by the beam shining on the outside of the solar cell and improves the energy transmission efficiency [106]. Moreover, the experimental results show that the WPT system using mirrors can effectively extend the application range of OWPT system and improve the flexibility of room effective charging [106].…”

“…Besides, solar cells convert light energy into electrical energy. The light source is driven by a DC working circuit to output a specific and stable solar battery voltage [106]. On this basis, a compact system can be used to achieve long-distance transmission, and no electromagnetic waves will leak into the environment outside the beam.…”

“…To improve the efficiency of the transfer system OWPT in remote and steep, authors propose a new system image OWPT numerical and experimental investigation and analysis that put forward the divergence angle of the power generation efficiency and system variables in the model space of the beam [106]. Furthermore, the OWPT system with multiple mirrors was considered, and the number of mirrors required for rooms of different sizes was studied.…”

“…The generation ratio of OWPT system with reflector is obtained when the reflector is 95% [106]. Figure 27b shows the power generation ratio of the system under a light source of 5 square mm.…”
