Abstract
A power supply system comprises: a switched-capacitor converter, a multi-tapped autotransformer, and an output stage. The multi-tapped autotransformer includes multiple primary windings. The switched-capacitor converter includes multiple circuit paths coupled to the primary windings. For example, a first circuit path includes a first capacitor; a second circuit path includes a second capacitor. The power supply further includes a controller that controllably switches an input voltage to the first circuit path and the second circuit path, conveying energy to the primary windings of the multi-tapped autotransformer. The output stage of the power supply is coupled to receive energy from a combination of the first primary winding and the second primary winding of the multi-tapped autotransformer. Via the received energy, the output stage produces an output voltage that powers a load.
