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 14):
ADC to DC voltage conversion system, comprising:\n a DC to DC conversion circuit, comprising:\n an inductor connected between an input node and an 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 bridge circuit connected between a node connecting the inductor to the first and second diodes and ground, the bridge circuit configured to generate a multi-level waveform on an internal node; \n a 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 capacitor is connected to the internal node; and \n a control circuit connected to the bridge circuit, the control circuit configured to supply the bridge circuit first and second non-overlapping control waveforms whereby an output voltage is generated at the output node from an input voltage at the input node, wherein the control circuit configured to turn the first switch on while concurrently providing the first and second non-overlapping control waveforms to the bridge circuit.
