摘要
开发了一种利用数字控制和Buck电路的电源模块,可将220 V的交流电转化为0~30 V的直流电。在电路设计方面,AC-DC变换电路和DC-DC变换电路作为主要工作电路,通过电路仿真来确定相关元件的参数;以单片机最小系统和外设电路作为控制电路。在控制系统方面,对电流传感器的反馈信号进行多次测量取平均值,并剔除突变值;为设定值设置了2个阈值,使实际测量值以不同的步进值接近设定值。
A kind of power-supply module which uses digital control and buck circuit was developed.The module can convert 220 V alternating current into 0~30 V direct current.In the aspect of circuit design,AC-DC and DC-DC transformations were major working circuits that determine parameters of relevant device through circuit simulation.While the control circuits are minimum system of SCM and peripheral circuit.In the aspect of control circuit,for feedback signal of current sensor,the power-supply module can obtain average value by multiple means and reject mutations at the same time.The module also set up two threshold values for set value and measured value can approach the sets value with different progressive values.
