Abstract
A method of operating a power converter in response to an interruption in an input power being provided to the power converter, as well as a power converter capable of performing such method and including a rectifier and an inverter coupled at least indirectly with one another, are disclosed. In at least some embodiments, the method includes (a) operating the rectifier so that energy stored in at least one first component coupled at least indirectly to at least one input terminal of the rectifier is transferred to an intermediate component coupled between the rectifier and the inverter, while the inverter is operated in a first disconnect mode, and (b) subsequently operating the inverter so that at least some of the energy transferred to the intermediate component is transferred to at least one output port of the power converter, while the rectifier is operated in a second disconnect mode.
