ABSTRACT:
The synchronous switching power supply can be employed in power supply system requiring multiple outputs and extremely high efficiency. The input signal may be AC or pulsating DC. A switching power supply with flyback converter includes an inductor coupled to ground for attaining a current. A switch is coupled between the AC input signal and inductor for selectively applying the AC input signal of one polarity to the inductor. A rectifier is coupled to the inductor for conducting the current and providing a first DC signal. Another converter converts the AC input signal of the opposite polarity into a second DC signal having the same polarity as the first DC signal. The first and second DC signals are applied to a capacitor which provides a DC output signal.
