Loop noise balance technique for CM EMI noise reduction of the full bridge LLC resonant converter
Abstract:
A full bridge LLC resonant converter can include: a full bridge circuit including a first input node and a second input node; a LLC resonant tank circuit connected to the first input node and the second input node; a transformer winding part connected to the LLC resonant tank circuit; a rectifier circuit connected to the transformer through a first output node and a second output node; and a capacitor connected between the first input node and the first output node. The LLC resonant tank circuit can include a resonant capacitor connected to the first input node, a resonant inductor connected to the resonant capacitor, and a magnetizing inductance connected between the resonant inductor and the second input node.
