【摘要】 在实现高压水射流清洗设备的自动控制过程中,存在着系统响应实时性差、稳定性低的问题。针对该设备的自动控制要求,从直流驱动电源的角度考虑,设计了相应的驱动电源结构。基于传统线性直流电源的结构,引入了改进的Buck变换器。通过MATLAB仿真表明,该电源具有更快的输出响应,功率转换损耗更低,输出电压电流波形稳定,输出功率大小可进行实时调节。在一定程度上改善了系统响应的实时性、稳定性,能够较好的满足射流清洗设备的应用需求。更多还原

【Abstract】 In the process of automatic control of high-pressure water jet cleaning equipment, there are two major problems, system response to real-time is poor and low reliability. In this paper, a special drive power structure is designed for the automatic control requirements of the device, which is considered from the perspective of DC drive power. Based on the structure of the conventional linear DC power supply, an improved buck converter is introduced. The simulation results show that the power supply has a faster output response and a higher power conversion efficiency, the output ripple is smaller. While the output voltage can be adjusted in real time. Which is improved the response to real-time and the reliability in a certain extent, it can be better meet the jet cleaning equipment driver needs.更多还原
