Patent attributes
An exemplary balance controlling circuit (100) includes a transformer (T11), a first capacitor (C11), a second capacitor (C22), a first inductor (TC11), and a second inductor (TC12). The transformer includes two inputs (41, 42) connected to an external circuit, a grounded first output (43) and a second output (44). The second capacitor (C12) includes a first port (121) configured to connect to ground, and a second port (122) connected to the second output of the transformer. The first capacitor (C11) includes a second port (112) connected to the second output of the transformer, and a first port (111) connected to the first inductor and the second inductor. The first inductor includes a first output port (I1). The second inductor includes a second output port (I2), and a third output port (I3).
