  • Common mode (CM) electromagnetic interference (EMI) filters for reducing radiated EMI in power converters
    Patent number: 11356011
    Abstract: Provided are examples of electromagnetic interference (EMI) filters for reducing radiated EMI in power converters. An example EMI filter includes a common mode (CM) choke located on an input cable connected to a first side of a converter a first set of Y-capacitors located between a primary ground (PGND) node of the converter and a secondary ground (SGND) node of the converter, and a second set of Y-capacitors located between the first side of the converter and the SGND node. A first shielding may be connected to the SGND node. One or more additional shieldings may be inside the first shielding and connected to one of the PGND node or the SGND node. The converter may be one or more of an isolated converter, an LLC resonant power converter, a Flyback converter, a forward converter, or a push-pull power converter.
