電源装置
Document Type and Number:
Japanese Patent JP4796101
Kind Code:
B2
Abstract:
A power supplying device (5) adapted for converting an input voltage. (V in ) into an output voltage (V o1 ) , said power supplying device (5) characterized by:
an output transformer (41) including an input coil unit (411) that is adapted for receiving the input voltage (V in ) , and an output coil unit (414) coupled electromagnetically to said input coil unit (411) and adapted for generating a first intermediate voltage (V o21 ) from the input voltage (V in );
a rectifying-and-filtering circuit (43); and
a voltage adjusting transformer (44) including a primary coil unit (441) connected-in parallel to said output coil unit (414) of said output transformer (41), and a secondary coil unit (442) connected in series between said output coil unit (414) of said output transformer (41) and said rectifying-and-filtering circuit (43), and coupled electromagnetically to said primary coil unit (441) so as to generate a second intermediate voltage (V o22 ) from the first intermediate voltage (V o21 ) obtained from said output coil unit (414) ; and
characterized in that said rectifying-and-filtering circuit (43) rectifies and filters a combined voltage that combines the second intermediate voltage (V o22 ) obtained from said secondary coil unit (442) with the first intermediate voltage (V o21 ) obtained from said output coil unit (414) into a second output voltage (V o2 ).
