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 7):
The AC to DC converter of  claim 6 , further comprising control circuitry connected to the first switch, the second switch, the third switch and the fourth switch, wherein the control circuitry is configured to generate the set of control signals such that:\n in a first half cycle, the first switch is on, the fourth switch is off, and the second switch and the third switch are turned on according to non-overlapping waveforms; and in a second half cycle, the second switch is on, the third switch is off, and the first switch and the fourth switch are turned on according to non-overlapping waveforms.
