Abstract

The invention relates to a semiconductor laser power supply based on a storage battery. A scheme that storage battery packs are connected with a direct current conversion module in series is adopted to supply power for the semiconductor laser; and the storage battery packs supply main power output while the direct current conversion module is relatively low in output power, so that the circuit design is relatively simple, the requirement on an electronic device is relatively low, and higher electric energy conversion efficiency can be realized more easily.

Description

technical field [0001] The invention relates to a battery-based semiconductor laser power supply, belonging to the field of semiconductor laser power supplies. technical background [0002] With the continuous improvement of the output power of semiconductor lasers, its application fields are also expanding. Some application fields require high mobility, such as field oil pipe, air pipe welding, power line deicing, etc., and the use of batteries for power supply is to improve its One of the effective ways of mobility. At present, the existing storage battery power supply scheme is to pass the output power of the battery pack through a direct current conversion circuit (DC-DC circuit) first, and then connect it to the semiconductor laser. When the output power of the laser reaches more than kilowatts, this solution has disadvantages such as complex circuit design, high requirements for electronic devices, low power conversion efficiency, and large volume and weight. For thi...
