FULL BRIDGE DC/DC CONVERTER CONTROL TECHNIQUES

摘要

The present disclosure describes full bridge power supply systems and control methods. In at least one embodiment, the full bridge power supply system may be driven utilizing a two-phase continuous conduction switching mode to control the inductor current. In another embodiment, the full bridge power supply system may be driven utilizing variably-configured three-phase continuous conduction modes to control the inductor current when an input voltage is within a window value to the output voltage. In another embodiment, the full bridge power supply may be driven using a four-phase discontinuous conduction switching mode to control the inductor current when a load current is below a current lower threshold.

1. A power supply system, comprising:
converter circuitry to receive an input voltage and generate an output voltage based on the input voltage; and switch controller circuitry to drive the converter circuitry utilizing a switching mode selected from a plurality of switching modes, wherein the switch controller circuitry is to determine a switching mode to select to drive the converter circuitry based on whether a difference between the input voltage and the output voltage is within a voltage window.
