Topology Selection For Bidirectional Energy Flow Applications Using WBG Devices


The paper provides an overview of the topology for bidirectional converters and discusses their different usage. Bidirectional energy flow applications are usually found in energy storage systems, battery systems, and can be categorized as grid-connected and DC-DC-connected. In grid-connected applications, two power conversion stages, which are power factor corrector (PFC) rectifier/inverter an... » read more

Considerations And Guidelines For Using High-Voltage CoolGaN Switches In Power Systems


The design of an electronic switched-mode power system has always been a complex task, requiring both knowledge and experience. With the appearance of gallium nitride (GaN), this task has even become more complex, because the electrical properties of GaN expand the room for possible system solutions. Particularly the lack of a physical body diode and the lateral device operation enable complete... » read more
