Alternating current to direct current converter i.e. galvanic isolation alternating current to direct current converter, for electrical distribution network of airplane, has transformer with secondary windings coupled to output line

摘要

The converter has a rectifier circuit (2) e.g. diode bridge, connected in series to a primary winding (5) of an isolation transformer (6) and to a cut-off-switch (T1) e.g. insulated gate bipolar transistor, connected to a pulse width modulation control circuit (10) at an input. The transformer includes a secondary winding (7) that is in a direction identical to the winding (5) and connected to an output line (8) of the converter via a diode (D4) and a filtering coil (L1), and a secondary winding (9) that is in a direction opposite to the winding (5) and connected to the line via a diode (D2).
