AC INTO DC VOLTAGE CONVERTER Russian patent published in 2016 - IPC H02M7/155 H02M7/23 H02M7/217 H02M3/335 

FIELD: electricity.

SUBSTANCE: invention can be used in secondary power sources as AC into DC voltage converter. AC into DC voltage converter includes primary winding of first transformer, which beginning is connected to anode of first diode, cathode is connected to anode of second diode, which cathode is connected to drain of first MIS transistor with n-channel, which gate is input for control signal U_contr1, which source is connected to second input of converter. Beginning of second transformer primary winding is connected to anode of third diode, which cathode is connected to anode of fourth diode, which cathode is connected to drain of second MIS transistor with n-channel, which gate is input for control signal U_contr2, and source is connected to first input of converter. Input capacitor is connected in parallel to inputs of converter. First output of storage capacitor is connected between cathode of first diode and anode of second diode, second output of storage capacitor is connected between cathode of third diode and anode of fourth diode. Beginning of secondary winding of first transformer is connected to positive output of converter, and end is connected to negative output of converter. First output of output capacitor is connected to positive output of converter, second output of output capacitor is to negative output of converter.

EFFECT: increased reliability and improvement of efficiency.
