ELECTRONIC TRANSFORMER Russian patent published in 2004 - IPC

FIELD: electronic engineering. SUBSTANCE: proposed bidirectional electronic transformer capable of voltage conversion following its waveform has pass-band ranging between dc and high-frequency currents when its equivalent windings are electrically isolated, this pass-band being independent of conversion frequency; it is noted for low dynamic loss and low level of external noise and has two alternately turned on parallel energy transmission channels with spanned on-time; each of them is, essentially, single-ended uncontrolled pulsed transformer converter with energy transferred in active phase (when switches are open) incorporating symmetric or asymmetric switches connected in series with all windings, as well as demagnetizing windings, switching circuits, and common control circuit. EFFECT: improved frequency characteristics, reduced size and mass. 4 cl, 3 dwg
