摘要

To meet the needs of portable laser rangeifnder driver module parameter adjustment, from the departure of conventional boost chopper circuit (Boost Chopper),this paper designs a high-powered DC booster circuit by appropriately changing the circuit parameters, the circuit structure. This paper carried out a detailed analysis of the boost principle and the role of every part of the circuit to find the condition of the high-voltage and deduced the formulas associated with the outputted high voltage, which draw the conclusion that high-voltage pulse is proportional to LC .The narrower the pulse width, the greater the voltage amplitude, the formulas and the circuit are used in the laser ranging application. The results of experiment, simulation and practical application verify the correctness and adaptability of the formulas and provide strong theoretical guidance and basis for the parameter adjustment of laser ranging voltage boost driver modules.%针对便携式激光测距升压驱动模块参数调整的需求，本文从传统的升压斩波电路(Boost Chopper)出发，通过适当改变电路参数、电路结构设计出一种直流高倍升压电路，并对升压原理、电路各部分的作用进行了详细分析，确定了高压产生的条件，导出了与高压输出相关的参数公式，得出高压脉冲宽度正比于LC ，高压脉冲宽度越窄，高压幅值越大的结论，给出了其在激光测距中的应用。实验、仿真和实际应用结果验证了该公式的正确性和适应性，为激光测距的升压驱动模块高压参数调整提供强有力的理论指导和依据。
