盐城工学院毕业设计说明书（2012） PAGE - 1 - 1000VA家用全自动交流稳压器设计 摘 要：二次电源作为负载的能量供应装置，在电路系统中起着非常重要的作用。尤其在我国，交流电网的电压波动较大、干扰较多，二次电源已成为许多电子设备不可缺少的供电装置。安全可靠、技术性能符合负载要求的电源，可使负载的功能得以充分发挥，否则，可能使负载的技术指标降低，甚至会损坏负载。为了延长用电设备的使用寿命，降低工厂的经济损失，应保证其供电电压的稳定。本课题通过研究自耦变压器的原理利用继电器的延时功能将输入电压为160 ~ 270V，变成输出电压220V±10%，实现家用电器的正常工作。针对用电设备对交流稳压电源的要求，提出了一种实用型的家用交流稳压电源稳压控制电路的设计方法及相关原理，稳压电源的主回路部分采用继电器分档来控制输入电压，使输出电压在AC220V左右，控制部分是采用集成运放LM324相关电路对不同取样电压采取不同处理方式来达到稳压控制效果，并增加了欠压、过压保护的自动切断功能。 关键词：继电器、交流稳压器、自耦变压器、延时功能 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 p
