Title:
TRANSFORMER UNIT
Document Type and Number:
WIPO Patent Application WO/2011/083767
Kind Code:
A1
Abstract:
Provided is a winding method for increasing productivity in a transformer unit which retains high-voltage components that constitute a voltage doubler rectifier for rectifying a high frequency and a high voltage from a secondary winding at the same bobbin at which a transformer is retained. The transformer has a bobbin (28) around which at least a primary winding (13) and a secondary winding (14) are wound, and a core (29) inserted into the center of the bobbin (28), and the transformer is mounted on a printed board. The transformer unit is provided with a component retention portion for retaining components at the outer peripheral portion other than the portion mounted on the printed board. The component retention portion has a voltage doubler rectifier (7) for rectifying a high frequency and a high voltage from the secondary winding (14), and the secondary winding (14) is connected to a lead terminal (24) of each high-voltage component constituting the voltage doubler rectifier (7), without a rib (21) on the bobbin (28).
