  • Semiconductor circuit for balancing energy sources
    Patent number: 12218534
    Abstract: A semiconductor circuit includes a first selection circuit which selects a first battery or a first capacitor, a second selection circuit which selects a second battery or a second capacitor, a voltage measuring circuit which measures a first voltage of the first battery or the first capacitor selected by the first selection circuit, and measures a second voltage of the second battery or the second capacitor selected by the second selection circuit, a controller which compares the first voltage and the second voltage to generate a comparison result, and a switching circuit which receives a signal based on a target output voltage, connects the first battery or capacitor selected by the first selection circuit, and the second battery capacitor selected by the second selection circuit in an interconnection relationship based on the comparison result to provide to an output terminal an output voltage responsive to the target output voltage.
