WebSep 22, 2009 · flyback和forward实际上是两类电源,而不是两种电源。. flyback包括各种boost,buck-boost以及Cuk电路,当然实用电路中的电感通常都拆开成为了隔离变压器(flyback变压器和通常变压器工作方式不同,里面包括了去磁绕组,实际上不是变压器而是个能量储存元件)的两个 ... WebA forward converter also usually requires an additional inductor L1 on the output side. However, through this, the output voltage can also have a lower ripple than that of a flyback converter at the same power level. Power management ICs such as the ADP1074 from Analog Devices offer a very compact solution for designing a forward converter.
