The Design of an AC/DC Off-Line Switching Power Supply Module
The control chip FSL106MR,which integrates SenseFET and PWM,is used to provide DC5V and 2 A power supply for the CPU and control circuit of the intelligent shuttle vehicle.According to the working principle of flyback topology circuit,the paper designed EMI filter circuit,bridge rectifier circuit,FSL106MR as the core control circuit and high-frequency high-voltage circuit to achieve AC input and DC 5 V stable output.The experimental results show that the output voltage ripple of the power supply module is small,stable and safe,and meets the design requirements.
