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.
