摘要
本设计采用美国Silicon General公司推出的SG3525开关电源控制芯片及MSP430F169型单片机作为微控制器而实现的Boost数控稳压电源。该数控电源通过键盘设定的输出电压值与对输出电压的检测值作为微控制器MSP430F169的输入,微控制器根据其两者的偏差值,调整其输出控制电源控制芯片SG3525,以期实现闭环稳压控制,从而达到对本设计开关电源输出电压的精密控制。
The design employs the switching control chip SG3525 and single chip MSP430F169 launched by US Silicon General as the microcontroller to achieve Boost NC power supply. In order to achieve a closed - loop stability pressure controlthus the precise control of the output voltage of the switching power supply of this design is achieved, the NC power supply takes the output voltage value set via the keyboard and the output voltage detection value as input of microcontroller MSP430F169 and the microcontrollerad- justs its output power supply control chip SG3525 according to the deviation of the above two values.
