A laser beam is an effective power and data carrier that offers inherent advantages in terms of the simultaneous transfer of wireless information and power, which is widely used in both the Internet of Things and the Internet of Energy. This paper proposes an adaptive high-power and high-efficiency laser-based simultaneous wireless information and power transfer system. This is achieved through the use of adjusted and modulated laser diode systems at the transmitter and multiplexed photovoltaic cells, a coupler, a filter, and a maximum power point tracking (MPPT) converter at the receiver. The interaction between the converter and the communication component is investigated theoretically and experimentally using a current-fed boost MPPT converter with the MPPT algorithm of perturbation and observation. The results indicate a maximum DC output power of 7.3 W at the receiver and a maximum MPPT converter efficiency of 84%. Additionally, at a data rate of 495 kbit/s, with a DC output power of 5.11 W, the bit error ratio is 2.62 × 10-4 for the binary amplitude shift keying modulation format, the MPPT converter efficiency is 88%, and the corresponding loss of communication is about 1% of the total transmitted power.
