A high-voltage distributed laser energy supply unit

Abstract

The invention relates to a high voltage distributed laser energy supply unit. The unit has a plurality of photovoltaic cells which are mounted on a substrate. The plurality of photovoltaic cells are in series connection and are in separate connection to two leads through two connectors which are mounted on the substrate. A heat sink is provided with an optical fiber joint box thereon, and the optical fiber joint box covers the substrate. The optical fiber joint box is provided with a protection cover thereon. An upper end surface of the optical fiber joint box is evenly distributed with the lower end parts of optical fiber joints, and the lower end parts extend inside the optical fiber joint box and each optical fiber joint is at a relative position to one photovoltaic cell, and the upper end of each optical fiber joint is connected to an output end of a laser through an optical fiber. According to the invention, each laser can input an optical power of 1-100W, and the conversion rate of the photovoltaic cell can reach 50 %, and high voltage and high power can be output after combination, and different lasers can be selected, or the power of each laser in an array laser can be separately adjusted, such that the current output by each cell matches. The unit increases product reliability and achieves maximum power output of the system.
