摘要
为实现光纤陀螺工程化,结合光源驱动电路的特点,设计了由大功率管FDW2520C构成的低功耗、小型化超辐射发光二极管(SLD)驱动电路.经实验验证:此电路在保证对光纤陀螺SLD光源高精度控制的条件下,电路效率明显得到提高, 最高效率达94 %, 功放管的最大耗散功率减小了36.3 %,经测试恒流精度为 0.01 %,光功率在-20～60 ℃范围内变化优于0.3 %,从而实现了光源驱动电路的低功耗和小型化目标,成为一种实用、可靠的光源驱动电路方案.
For the purpose of improving practicability of FOG, and considering the characteristics of driving of the light source of FOG,the low-power-consumption and miniaturization circuit with super luminescent diode （SLD） composed of FDW2520C chip is designed. Proven by experiments ,at the condition of high-precision controlling, the efficiency of the improved circuit is increased to 94% and the maximum power consumption of the new poweramplifying chip reduced 36.3%. The current precision is as high as 0.01% and the variety of light power is less than 0.3%, while in a ambient temperature range of -20～60℃. So the low-power-consumption and miniaturization aims are realized and it is a oractical and reliable scheme.
