| Abstract: | Flyback converter possesses simple configuration and low cost and can operate in wide scope of input voltage, so it is very popular in small-power charger and adapter. However, how to design transformer is vital and the efficiency can boost if the transformer is made perfectly. This paper mainly study design method for flyback converter operating in discontinuous-mode, presents design principle of the transformer and calculating formula of the key parameters based on the operating basic of flyback converter. |
