摘要
针对传统信号源输出电压较低,负载能力弱且无法闭环稳压、稳频的缺点,研制了一种输出电压有效值为40 V,负载电流为1 A的高稳定度纯净正弦波功率信号源,以适应陀螺测试等系统的需求.本文对该功率信号源系统结构和电路原理进行了详细的分析.样机实验结果表明:该信号源具有功率大、稳定度高,准确度高和低谐波含量的优点,具有良好的应用前景.
The traditional signal source has the low output voltage, weak load ability, and cannot realize closed - loop voltage and frequency stabilization. In this study we developed a kind of high-stability pure sine wave power signal source with 40 V effective output voltage value and 1A load current for adapting to the gyro test system requirements. The system structure and circuit principle of the source are analyzed in detail. Experimental prototype shows that the signal source has high power, high stability, high accuracy and low harmonic content. So it has good application prospects.
