摘要： 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.

摘要： A protection scheme to protect pulse width modulated drives is described. The scheme is implantable in both hardware and software and combinations thereof. The semiconductor devices of the drive are protected from transient signals such as power line spikes and loss of line. The present scheme uses an adaptive technique to determine the normal or steady state distortion (transients and harmonics) value in an unfiltered power signal. The present distortion value is compared to the normal distortion. If the present distortion exceeds the steady state value by a given amount, then the drive is placed in freewheel mode to protect the semiconductor devices in the drive.
摘要翻译：描述了保护脉宽调制驱动器的保护方案。该方案可植入硬件和软件以及它们的组合。驱动器的半导体器件可以免受诸如电源线尖峰和线路损耗等瞬态信号的影响。本方案使用自适应技术来确定未滤波的功率信号中的正常或稳态失真（瞬变和谐波）值。将当前失真值与正常失真进行比较。如果当前的失真超过稳态值一定给定量，则将驱动器置于续流模式以保护驱动器中的半导体器件。
