FIELD: electronic equipment.SUBSTANCE: invention can be used as converter of constant voltage for secondary power systems. Two-stroke flyback-to-DC converter includes primary winding of first transformer, end of which is connected to drain of the MOS transistor with n-channel and with integrated diode, a source which is connected to negative pole of input voltage, and gate which is input for control signal U; beginning of primary winding of second transformer is connected to source of second MOS transistor with n-channel and with integrated diode, a drain of which is connected to positive pole of input voltage, and gate is the input for control signal U. One output of storage capacitor is connected between end of the first transformer and drain of first MOS transistor with n-channel and with integrated diode, second output is connected between beginning of primary winding of second transformer and source of second MOS transistor with n-channel and with integrated diode. Beginning of secondary winding of first transformer is connected to negative terminal of load, end of which is connected to anode of first rectifier diode cathode is connected to positive outputs of load, output capacitor, a negative output of which is connected to negative terminal of the load. Start of second transformer secondary winding is connected to negative terminal of load, end of which is connected to anode of second rectifier diode cathode is connected to positive terminal of load.EFFECT: technical result is increased reliability and higher efficiency.1 cl, 2 dwg |
