摘要：A lot of ITS (Intelligent Transportation System) devices have been installed at roadside to collect traffic volume, travel speed, video, etc. The RSE (Roadside Equipment) is installed at the road shoulder and operated by receiving electricity from an ambient transformer. However, the input electricity to RSE is being provided unstably because of the physical distance between RSE and transformer, fluctuations around the electric power load etc. Generally, RSE has a device that rectifies unstable input electricity. However, when the input voltage is changed significantly, it exceeds the conversion range of a voltage converter and affect the controller. In this study, we propose a method that provides stable voltage for unstable input voltage and present the result of improvement scheme through the experimental study for the developed device.
