摘要： A power supply device includes first and second power factor correctors, and first and second resonant circuits. The first and second power factor correctors are for receiving an alternating current (AC) input voltage, and are driven by first and second driving signals for rectifying the AC input voltage to generate first and second driving voltages, respectively. The first and second resonant circuits are coupled to the first and second power factor correctors for receiving the first and second driving voltages, respectively, and have output sides that are coupled in parallel for outputting an output voltage. The first power factor corrector and the first resonant circuit in combination is parallel-connected to the second power factor corrector and the second resonant circuit in combination.

摘要： A center-tapped transformer includes tubular first and second spools, a primary winding unit, and first and second secondary winding units. The first spool has a first surrounding wall, a first pin-mounting wall, and a first pin set mounted on the first pin-mounting wall. The second spool has a second surrounding wall, a second pin-mounting wall, and a second pin set mounted on the second pin-mounting wall. The second surrounding wall has an inner diameter larger than an outer diameter of the first surrounding wall. The primary winding unit is wound on one of the first and second surrounding walls. The first and second secondary winding units are wound on the other one of the first and second surrounding walls.

摘要： A center-tapped transformer includes a spool, a first primary winding unit, and first and second secondary winding units. The spool has a surrounding wall defining a spool axis, and a partition plate unit extending in radial outward directions from the surrounding wall so as to divide the spool into axially extending first and second spool parts. The partition plate unit cooperates with the surrounding wall to define at least one notch. The first primary winding unit surrounds the first spool part and passes through the notch to surround the second spool part. The first and second secondary winding units are disposed on one side of the first primary winding unit and surround the first and second spool parts, respectively.
