Abstract:
A DC to DC converter uses a multi-level boost converter topology. In addition to the input voltage being connected to an output node through a boost inductor in series with a pair of diodes, a bridge circuit generates a multi-level waveform on one side of flying capacitor, which is on the other side connected between the series connected diodes. The boost converter topology maintains low voltage stress on its components under abnormal conditions on the output node and allows for simple pre-charging of the flying capacitor.

Claim (Index 19):
A method, comprising:\n receiving an input voltage at an input node; generating from the input voltage an output voltage at an output node, generating the output voltage comprising:\n generating first and second non-overlapping control waveforms; \n applying the first and second non-overlapping waveforms to a bridge circuit; and \n generating by the bridge circuit from the first and second non-overlapping waveforms of a multi-state waveform at an internal node of a DC to DC voltage converter, the DC to DC voltage converter including:\n an inductor connected between the input node and the output node; \n first and second diodes connected in series between the inductor and the output node, configured to allow current to flow from the inductor to the output node; \n a first capacitor having a first plate and a second plate, the first plate connected to a node between the first and second diodes and the second plate connected to the internal node \n a third diode connected between the internal node and an intermediate voltage node, configured to allow current to flow from the internal node to the intermediate voltage node; and \n a first switch through which the second plate of the first capacitor is connected to the internal node, \n wherein the bridge circuit is connected between a node connecting the inductor to the first and second diodes and ground, \n \n the method further comprising: prior to generating the output voltage at the output node, performing a pre-charge operation, the pre-charge operation including:\n receiving the input voltage at the input node while setting the first switch off.
