Open Loop Soft-Switching Full-bridge Converter for Solid State Transformer Application

One of the pillars of the Power Electronics Innovation Center (PEIC) is the power converters design and testing for grid application. The development of power systems and the move to smart grid have increased the need for new technologies. In this scope, solid-state transformers have been proposed as a suitable alternative to conventional transformers copper and iron transformers. Solid-state transformers (SST) are among the equipment based on power electronic converters that in addition to better performance than conventional transformers provide a variety of other services.
