| 摘 要： | 使用常用的与非门电路和双极性晶体管来制作开关电源.用14011B构成PWM方波电路,通过控制双极性晶体管的开断,把高的电信号转换成开关信号,通过近似无损耗的滤波,得到降低了的电源.利用负反馈,提高了输出电压的精度,抑制了电源纹波.

| Abstract: | Using common NAND gate and bipolar transistor circuit to produce switching power supply.14011B constitutes a square wave with PWM circuit,and bipolar transistor controls the breaking of the high-loaded into the signal switch signal,through the filter,the power has been reduced.The use of negative feedback to improve the accuracy of the output voltage checks the power supply ripple. |
