Abstract:
AC to DC converters, more specifically Power Factor Correction (PFC) circuits, using a multi-level waveform and hybrid devices are presented. From an AC voltage input a multi-level waveform is generated, which is used to generate high and low DC output voltage levels. The multi-level waveform is connected to the DC outputs through a correpsonding intermediate node by an initial switch, and from the intermediate node to the correpsonding output by a hybrid device. The hybrid device includes a first current path, such as a series connected switch-diode pair, in parallel with second current path of a relativley faster and lower current device, such as a diode. The resultant arrangement can use devices having lower voltage ratings relative to typical PFC cirucit designs.

Claim (Index 9):
The AC to DC converter of  claim 7 , wherein:\n the first circuit element includes a fifth switch connected between the mid-level node and the first intermediate node; the second circuit element includes a sixth switch connected between the second intermediate node and the mid-level node; the control circuitry is further connected to the fifth switch and the sixth switch; and the control circuitry is further configured such that in the first half cycle the fifth switch is off and the sixth switch is on, and such that in the second half cycle the sixth switch is off and the fifth switch is on.
