Abstract

Laser Wireless Power Transmission (LWPT) is one of the leading technologies in long distance and high power Wireless Power Transmission (WPT). One of the most important parts of this technology is the transmitter part, which includes the laser and the driving circuit. In this study, a low cost transmitter is proposed by using pulse mode Laser Diodes (LDs). 5 LDs were operated by keeping them at 85 µs of cut-off at 15 µs of transmission, and a 100 µs operating period was obtained by leaving 5 µs of dead time between each LDs to provide cooling as they are using common cooling plate. The proposed system has been designed and experimentally verified in this paper
