摘　　要：为满足车载光电经纬仪对伺服控制系统控制精度、稳定性以及质量体积等方面的要求,针对伺服控制系统主电源开展了相关研究。主电源作为伺服控制系统的能量供给单元,其稳定性决定了伺服控制系统的稳定性,继而影响伺服控制系统的跟踪精度以及跟踪频率等指标。文章从电源设计要求、主电路、最大脉宽限制电路、PWM控制电路、电压电流检测电路以及电压反馈控制电路6个方面进行了研究,同时依据此方法设计电源。测试结果表明,电源输出为48 V DC,输出功率为2 400 W,峰峰值为310 mV,重量为13.8 kg,体积为350 mm×200 mm×110 mm。In order to meet the requirements of vehicle photoelectric theodolite on the control precision,stability,weight and volume of the servo control system,relevant research was firstly carried out on the main power supply of the servo control system.As the energy supply unit of the servo control system,the stability of the main power supply determined the stability of the servo control system.Then the tracking precision and tracking frequency of the servo control system were affected.In this paper,the design requirements of the power supply,the main circuit,the maximum pulse width limiting circuit,PWM control circuit,voltage and current detection circuit and voltage feedback control circuit were described.At the same time,the power supply was designed according to this method,and the test results were obtained:the power output is 48V DC;the output power is 2400W;the peak-to-peak value is 310mV;the weight is 13.8kg;the volume is 350mm×200mm×110mm.
