  "textContent": "An uninterruptible power supply apparatus includes an AC/DC converter that converts AC power supplied from a commercial AC power supply into DC power and supplies the DC power to a DC line, a DC/AC converter that converts the DC power received from the DC line into AC power and supplies the AC power to a load, a DC/DC converter that provides and receives DC power between the DC line and a battery, and a bidirectional converter that, in high-speed charging of the battery, operates in cooperation with the AC/DC converter, converts the AC power supplied from the commercial AC power supply into DC power, and supplies the DC power to the DC line. This can prevent a shortage of DC power during a high-speed charging operation and enables high-speed charging of the battery while supplying rated power to the load.",
