| Abstract: | Forward-type power converter is widely used in small and medium-sized power supplies.Magnetic integra-tion technology helps to reduce the current ripple through windings,reduce the switching losses of components and improve the power efficiency.The internal magnetic fluxes can be effectively configured to lessen AC fluxes and DC bias,reduce the weight and volume of the power supplies.The different magnet-ic schemes in forward converters are compared in detail,including discrete magnetics,integrated magnetic... |
