| Abstract: | Compares the merits and limits of three converters(50 W) from magnetic elements, electroinc stress of power device, magnetic resetting, output ripples and output characteristics. Their parameters are also presented for comparison. It is concluded that Fly Forward converter has more advantages over single ended converter, such as low voltage stress, small magnetic element, low volume and weight, low output ripple and high reliablity. |

| Keywords: | converters pulse width modulation(PWM) continue current mode(CCM) discontinue current mode(DCM) electronic stress |
