Title:
ELECTRONIC APPARATUS FOR POWER CONVERSION, AND POWER CONVERSION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/164125
Kind Code:
A1
Abstract:
An electronic apparatus according to various embodiments may comprise: an energy storage circuit including at least one capacitor connected in series with a battery to accumulate charges; a switched capacitor which transmits the charges from the energy storage circuit to an output circuit; a switched inductor for controlling an output voltage; and a processor operatively connected to the switched capacitor, the switched inductor, and the energy storage circuit. The processor may measure a voltage of the battery, a voltage of the energy storage circuit, and an output voltage of the electronic apparatus. The processor may control the output voltage through the switched inductor and control the energy storage circuit to accumulate the charges. When the charges are accumulated in the energy storage circuit and the voltage of the energy storage circuit is greater than or equal to the output voltage, the processor may control, through mode switching of the electronic apparatus, excess charges of the energy storage circuit to be transmitted to the output circuit via the switched capacitor.
