摘要： A power converter includes a power input configured to receive input power from an AC power source, a power output configured to provide output power to a load, a battery interface configured to exchange DC power with a battery, and power converter circuitry. The power converter circuitry is adapted to, in a first interconnection configuration, convert the input power into the DC power at the battery interface, and, in a second interconnection configuration, convert the DC power at the battery interface into the output power. The power converter circuitry has a power line, a transformer, a first connection node switchably connected to the power line in the first interconnection configuration and switchably connected to the transformer in the second interconnection configuration, and a second connection node switchably connected to the transformer in the first interconnection configuration and switchably connected to the power line in the second interconnection configuration.
