摘要： A power system is disclosed for receiving dual alternating current sources and delivering direct current to drive a load. The power system comprises four power supplies and two transfer switch modules, any of which may be removed and replaced without disabling the power system. Three of the power supplies deliver current to drive the load while the fourth is redundant. A transfer switch control circuit activates relays within the transfer switch modules, in response to a change in the voltage maintained by one or both AC sources. As long as one of the AC sources maintains a voltage within a predetermined voltage range, three of the power supplies deliver current to drive the load.

摘要： Methods and systems may involve detecting an output voltage of a voltage regulator and sensing an inductor current corresponding to a saturating output inductor of the voltage regulator. A switching frequency signal can be generated based on the inductor current, wherein the voltage regulator may be controlled based on the output voltage and the switching frequency signal. In one example, the switching frequency signal sets a first switching frequency if the inductor current is below a saturation current threshold, and sets a second switching frequency if the inductor current is above the saturation current threshold, wherein the second switching frequency is less than the first switching frequency.
