Gallium nitride has the advantage of high frequency characteristics. Currently, the gallium nitride fast charging frequency starting at exceeding 100KHz, even as high as 300KHz. As the power devices' switching frequency increases significantly, various parasitic parameters gradually affect the fast charging efficiency under high frequency conditions.How to eliminate the influence of parasitic para...

In recent years, as power grids have increasingly advanced toward intelligent and automated operation, real-time monitoring of power systems—such as insulation monitoring of transmission lines, fault location in distribution networks, and overhead line icing detection—has become a critical focus. Given the high voltage levels of transmission lines, monitoring equipment is often exposed to prolonge...

In our previous discussion, we noted that the magnetic core adopts an open-gap design, and through optimal parameter selection, the dead-zone current is effectively reduced. By analyzing the variation patterns of load and number of turns, we employed a method combining multiple turns with parallel resistors to suppress magnetic saturation. This approach successfully addresses the challenge of stab...
