FIELD: electrical engineering; power supplies for various on-board radio-receiving devices of ground, marine, and aerospace systems. ^ SUBSTANCE: proposed converter designed to supply with power high-sensitivity radio receivers, frequency synthesizers, standard signal generators, research apparatuses, and the like has control circuit incorporating first and second outputs, each being connected to respective series-connected resistor, penultimate stage, capacitor, as well as output-transistor working point path shaper. First and second outputs of each shaper are connected to base and collector of respective output transistor; primary winding of output transformer is inserted between collectors of mentioned transistors and its center tap functions as device input; each secondary winding of transformer is connected through respective output rectifier and output filter to respective output terminal of converter. ^ EFFECT: reduced field strength of converter-induced electromagnetic noise due to generating smooth-angle trapezoidal-waveform voltage across collectors of output transistors. ^ 1 cl, 1 dwg |
