Abstract:
A hybid resonant DC to DC converter uses an LLC or other resonant structure on the primary side, applying a two state waveform to one end of the resonant structure and a multi-state waveform to the other end of the resonant structure. The waveforms are at or near the resonant resonant frequency and the output voltage level is regulated by varying the shape of the multi-state waveform by varying the duty cycle of the switches used to generate it. The allows the converter to operate near or at its optimal resonant point, resulting in higher efficiency, over a wide range of regulated output voltage levels.

Claim (Index 12):
A direct current to direct current (DC to DC) voltage conversion system, comprising:\n a DC to DC conversion circuit, comprising:\n an input voltage node; \n a first bridge circuit connected to the input voltage node and a ground node, and configured to provide a first waveform to a first internal node; \n a second bridge circuit connected to the input voltage node, an intermediate voltage node and the ground node, and configured to provide a second waveform to a second internal node, the second waveform being a multi-state waveform; and \n an intermediate circuit including a first inductor connected between the first internal node and the second internal node, the first inductor configured to be driven by the first and second waveforms to provide an output voltage to an output voltage node; and \n a control circuit connected to the first bridge circuit and the second bridge circuit and configured to supply thereto a set of control signals having a cycle of a first frequency, wherein the control circuit is configured to supply a set of control signals to the DC to DC conversion circuit whereby the first bridge circuit applies to the first internal node the first waveform of the first frequency and having at least a high value and a low value, whereby the second bridge circuit applies to the second internal node the second waveform having at least a high value, an intermediate value and a low value, and wherein the first and second internal nodes are not concurrently at either of the corresponding high values or the corresponding low values.
