  • Publication number: 20250192678
    Abstract: Disclosed are a power conversion device and a method for power conversion. A voltage conversion device includes a voltage input terminal, a voltage output terminal, a voltage detection selector, a buck conversion circuit, and a bypass control circuit. The voltage detection selector detects whether the input voltage is greater than a predetermined voltage to generate a first enable signal and a second enable signal. The buck conversion circuit receives the second enable signal. When the second enable signal is enabled, the buck conversion circuit converts the input voltage to a converted voltage that is less than or equal to the predetermined voltage, and provides the converted voltage to the voltage output terminal. The bypass control circuit receives the first enable signal. When the first enable signal is enabled, the bypass control circuit provides the input voltage from the voltage input terminal to the voltage output terminal.
