MULTIPLE-INPUT ISOLATED PUSH-PULL CONNECTED POWER CONVERTERS

摘要

A multiple-input power converter transferring energy from multiple input sources to a load. The multiple-input power converter utilizes a push-pull converter that isolates loads from sources by a transformer in the output rectifier stage. The isolation increases the safety of the system and provides a wider range of sources-to-load voltage transfer ratios. Furthermore, the multiple-input power converter utilizes a lower number of components in comparison to previously designed multiple-input power converter topologies as well as has a lower control circuit implementation cost when compared to previously designed soft-switching multiple-input power converters.
