1000VA家用全自动交流稳压器设计 摘 要： 1000VA household full automatic AC voltage stabilizer design Abstract: secondary power sources took the energy supply device of the load, is playing a very important role in the circuitry. Especially in our country, in alternate current network the voltage is more fluctuations, and more interference, secondary power sources have become indispensable power supply device in many electronic devices. Safe and reliable, with technical performance requirements of the power load, the load can be fully functional play, or else possibly causes the load the technical specification to reduce, even can damage the load. in order to lengthen the service life of current collector, reduces the economic loss of factory . should guarantee its power line voltage the stability. Especially in the industrial field environment, the electrical network quality is especially bad, the electrical network waveform distortion is serious. Therefore, it is very necessary to develop a highly efficient and reliable ac voltage-stabilized source as the second power supply of load. This paper through the research of the autotransformer principle using the relay function input voltage of 160- 270V, into the output voltage 220V ? 10%, realize the normal work of household appliances. By the consumer requirement on alternating voltage stabilizing power supply, we put forward a kind of design procedure and relevant principles of a practical voltage stabilizing controlled circuit of household alternating constant voltage power supply. The main loop of constant voltage power supply is adopted relays to control input voltage, and get an output voltage in about AC220V. The controlling part is used by integrated operational amplifiers taking different process to different sample voltage, which results in voltage stabilizing controlling. Also, it can bring about the function of cutting off circuit automatically when it is over-voltage or back-voltage. Key words: relay, AC voltage regu
