| Abstract: | The flyback switching power supply principle is described.The power supply design,the calculation methods about the high-frequency transformer,the primary and secondary of transformer and critical inductance are given.The relationship between the flyback switching power's voltage quality and MOSFET switching is studied.The experimental results show that this design has better voltage regulation and load regulation,higher efficiency and smaller voltage ripple compare with the former design. |
