Abstract: A power conversion apparatus and an energy storage system, including a power conversion circuit, a first power terminal, a second power terminal, and a third power terminal. The power conversion circuit includes a first positive end, a first negative end, a second positive end, a second negative end, and at least one power device. The first negative end and the second negative end have a same potential. The power conversion circuit is configured to convert a first voltage input by a first device into a second voltage and output the second voltage to a second device. The first power terminal is connected to the first positive end, the first negative end or the second negative end is connected to the second power terminal, and the third power terminal is connected to the second positive end.
