摘要
通过分析典型恒压源的电路结构和工作原理,研究了影响恒压源精度的一些关键因素,研制了一款基于HV9120输出电压为12 V的恒压源样机。并测试了样机输入电压在165-265 V范围内变化时,其输出电压的变化情况。实测结果表明,输出电压基本保持稳定,满足稳压的设计要求。
Through the analysis of the circuit structure and working principle of typical constant voltage source,some key factors affecting the accuracy of constant voltage source are studied and a constant voltage source prototype based on HV9120 with the output voltage 12 V is developed. The output voltage change is tested when the prototype input voltage changes within 165-265 V. The test results indicate that the output voltage remains stable and meets the stable voltage design requirement
