摘　　要：为解决旋转导向系统中无源二极管整流器导致交流端电流谐波大、直流总线电压缺乏可控性,以及功率因数偏低的问题,提出应用于旋转导向系统的有源前端整流器方案。通过对旋转导向系统中发电整流模块的电压稳定性、电磁兼容性及功率管理的分析研究,构建了有源前端整流器仿真模型,并对其在空载到满载及动态载荷变化下的性能进行仿真;实现了有源前端整流器的系统设计,并在实验室内搭建了系统测试平台。测试结果表明:发电机端电流谐波得到有效抑制,电流波形呈现高保真正弦特性,电流总谐波失真系数THD小于5%;直流总线电压精准控制在400 V;稳态下,直流总线电压展现零静态误差特性,系统功率因数大于0.9,确保高效率运行,各项参数符合设计指标。该有源前端整流器解决了旋转导向供电系统中由于非线性元件影响系统稳定性和效率的问题,提升了发电利用率,使旋转导向系统运行更加高效。Passive diode rectifiers in rotary steering systems are deficient for high AC current harmonics,lack of controllability of DC bus voltage,and low power factor.This paper presents an active front-end rectifier scheme for rotary steering systems.By analyzing the voltage stability,electromagnetic compatibility and power management of the power generation rectifier module in the rotary steering system,a simulation model of the active front-end rectifier was built,and its performance under the conditions of no-load to full load and dynamic load was simulated.Moreover,a system design of the active front-end rectifier was completed,and a system test platform was constructed in the laboratory.The test results show that the current harmonics at the generator end is effectively suppressed,the current waveform exhibits high fidelity sine characteristics,and the total harmonic distortion(T HD)of the current is less than 5%.The DC bus voltage is precisely controlled at 400 V.In steady state,the DC bus voltage exhibits zero static error characteristics,and the system power factor is greater than 0.9,ensuring efficient operation.All parameters meet the design indexes.The proposed active front-end rectifier solves the problems of system stability and efficiency affected by nonlinear components in the rotary steering power supply system,improves power generation utilization,and makes the operation of the rotary steering system more efficient.
