Abstract


With the development of scientific technology and industrial & agricultural production in modern society, increasingly high demands have been proposed on power supply technology. The stability of power supply is directly related to the working quality and efficiency of the entire electronic & electric circuit and device, thus power supply technology with high stability has vitally important research significance in both military and civil fields.Traditional stabilized power supply usually refers to chemical power supply like battery; it is widely used in situation which requires ordinary stability of power supply due to its inherent pure direct current property. However, the inherent stability of battery can not meet the requirement under situation with the most demanding on stability of power supply, including voltage measuring and laser power supply, etc, thus to stabilize the voltage again by basing on the theory of high stabilized power supply, so as to meet the output requirement.Discourse has been made in the article for the design of power supply sub system of double light source based laser light detecting system. A detailed discussion has been made to the planned requirement of entire circuit, plan of electric circuit, design of electric circuit, layout and test of electric circuit by using module power supply as basic unit in construction of system circuit.According to the requirement of the subject, firstly, requirements of systematic power supply is divided into two modules, namely stabilizing power supply and constant-current supply, specific requirement of each output shall be found out after subdivision of the two modules; and then, according to the output requirements of the system, components and parts can be selected and feasibility test can be carried out on each design circuit for each output; finally, the entire system shall be integrated on one circuit board and joint debugging shall be done, problems such as interference, etc. can be solved. For problems can not be completely solved at present, possible ways for solving shall be disclosed by basing on bibliographic search, so as to put forward expectation for future improvement.
