Abstract
With the continuous development of human society, the increasing scale of lighting, the numbers are growing, which is to improve the region's economic development played an important role. But with the coming of a substantial increase in energy consumption, lighting energy consumption of electricity has become big. In recent years a substantial upgrade in energy prices, so that lighting power consumption to become a major economic burden on the user. This paper is a kind of STC microcontroller as the control of intelligent lighting Saver, AC chopper and high frequency switching technology that uses high frequency switching IGBT module as the device's overall higher conversion efficiency. AC chopper and high frequency switching technology to achieve the AC voltage regulator that can output phase with the grid voltage, the voltage waveform waveform consistent with the output voltage harmonic content is low, the dynamic characteristics of fast response time.AC chopper with series comprising the combination of step-down transformer Saver, the use of cascade form of compensation, so the equipment capacity is only part of the capacity equal to saving, greatly reduces the volume Saver reduces the loss . No matter how voltage lighting saver that fluctuations can be of use the input voltage to control the lighting at the best value to maximize energy savings.
