| Abstract: |
| The basic theory of switching power supply was
introduced. The Buck converter has been analyzed and tested. The model of the system was
established on the basis of experiments. The stability of the system was also analyzed. A
feasible scheme of PWM high frequency switching power supply was put forward. |
