摘要： A power conditioner includes an input configured to be coupled to a main-power source and an output configured to receive power from within the power conditioner from the main-power source, a backup-power source, or both. The power conditioner includes an inverter, at least one processor, and a memory storing instructions that, when executed by the processor, cause the processor to perform a method. The method includes receiving an inverter-off signal, receiving an output-voltage level above a threshold output-voltage level, and preventing activation of the inverter in response to at least receiving the inverter-off signal and the output-voltage level above the threshold output-voltage level.

摘要： According to one aspect, a DC power supply is provided. The power supply includes a first input configured to be coupled to an AC power source, a second input configured to be coupled to a battery, an output, a transformer, and a controller coupled to the transformer. The transformer includes a first winding configured to be coupled to the first input, a second winding configured to be coupled to the second input, and a third winding configured to be coupled to the output. The controller controls, in a first mode, the first winding to generate, based on power received from the AC power source, a first voltage across the second winding to charge the battery, and a second voltage across the third winding, and control, in a second mode, the second winding to generate, based on power received from the battery, a third voltage across the third winding.
