  • Publication number: 20240072633
    Abstract: The present invention provides a resonant switched capacitor voltage converter (RSCC), which is coupled to and operates synchronously with another RSCC. The RSCC includes: plural switches, a resonant inductor, a resonant capacitor, and a control circuit. The control circuit controls the switches, so that the resonant capacitor and the resonant inductor are connected in series to each other, to perform resonant operation in a switching period, thus converting an input voltage to an output voltage. The control circuit generates a zero current signal and a first synchronization signal when a resonant inductor current flowing through the resonant inductor is zero. The control circuit turns off at least one corresponding switch according to the zero current signal. The control circuit turns on at least one corresponding switch according to the zero-current signal and a second synchronization signal, so that the RSCC operates in synchronization with at least another RSCC.

  • Patent number: 10673104
    Abstract: A method is provided for testing a semi-finished battery cell. The semi-finished battery cell is charged with a constant current when a voltage difference between the first conductor and the second conductor is less than a voltage threshold. The semi-finished battery cell is charged with a constant voltage when the voltage difference between the first conductor and the second conductor is equal to or larger than the voltage threshold. An overall electric quantity is obtained after a default time period, wherein the overall electric quantity is an electric quantity charged to the semi-finished battery cell with the constant current during the default time period. Accordingly, an insulation related to electrodes of the semi-finished battery cell is determined as poor when the overall electric quantity is larger than an electric quantity threshold.
