Analyzed secondary power sources with stabilization of output voltage by width-pulse modulator with transistor key, laden on output pulsed transformer, that allows to reach 300 Wt/dm3 under CUE before 70%. Considered resonant scheme AC/DC converters with use LC-sidebars. Install that resonant scheme has more high efficiency, enable to enlarge a transformation
frequency before 2 MHZ, that allows for the power of load before 100 Wt reach 930 Wt/dm3 under CUE before 87%.
