Abstract:
An AC-DC converter  1  has, e.g.: a primary winding  11  to which an alternating-current input voltage Vi is applied; a secondary winding  12  magnetically coupled with the primary winding  11 ; a bidirectional switch  20  connected in series with the primary winding  11 ; a resonance capacitor  30  connected in parallel with at least one of the bidirectional switch  20  and the primary winding  11 ; a resonance inductance component (e.g., a coil  120 ); a full-wave rectification circuit  40  performing full-wave rectification on an induced voltage appearing in the secondary winding  12 ; and a smoothing capacitor  50  smoothing the output of the full-wave rectification circuit  40 . The alternating-current input voltage Vi is converted directly into a direct-current output voltage Vo, with both a forward voltage and a flyback voltage extracted from the secondary winding  12 . The converter  1  further has a switch  200  switching the number of turns of the primary winding.

Claim (Index 12):
The AC-DC converter according to  claim 9 , wherein\n the switch has a common node thereof connected to the bidirectional switch, the switch having a first selection node thereof connected to a first tap of the second primary winding, the switch having a second selection node thereof connected to a second tap of the second primary winding.
