摘要
为了解决简易串联稳压电源输出电压受稳压管稳压值得限制无法调节,电路的稳压效果也不够理想的问题。本设计增加了负反馈过程,把调整管的负载用恒流源代替,同时为保证电源安全工作设计了过流保护部分。此设计可满足电源现阶段实用产品的一般需求。
Because of restrictions by the regulator voltage value, simple series power supply can not adjust the output voltage,while voltage regulation circuit is also not stable enough. In order to solve these two problems, we increase the negative feedback block and employ a constant current source as the load of regulator. Meanwhile, an over current protection section is added to ensure the safety of the power supply. This power supply is proven to meet the general needs of the present stage.
