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 13):
A method, comprising:\n receiving an alternating current input voltage at an input node of an alternating current (AC) to direct current (DC) converter; and respectively generating first and second output voltages at first and second output nodes of the AC to DC converter from the alternating current input voltage, the AC to DC converter comprising:\n a first hybrid device, comprising first and second current paths in parallel from a first intermediate node to a first output node, wherein the first current path is a faster switching, lower current rated path than the second current path; and \n a second hybrid device, comprising third and fourth current paths in parallel from a second output node to a second intermediate node, wherein the third current path is a faster switching, lower current rated path than the fourth current path, \n wherein generating the first and second output voltages includes:\n when in a first half cycle, setting the second intermediate node to a voltage level between the first output voltage and the second output voltage and applying a pulse width modulated waveform at the first intermediate node; and \n when in a second half cycle, setting the first intermediate node to the voltage level between the first output voltage and the second output voltage and applying a pulse width modulated waveform at the second intermediate node.
