An Uninterruptible Power Supply (UPS) including an input configured to receive input AC power having an input AC voltage, a backup power input configured to be coupled to a backup power source and to provide DC power to the backup power source for charging, a positive DC bus and a negative DC bus, the positive and negative DC busses being galvanically coupled to the backup power input, and a converter coupled to the input, the backup power input, and the positive and negative DC busses, the converter including a first inductor, a second inductor, a first converter switch configured to couple the first inductor to a neutral connection, a second converter switch configured to couple the second inductor to the positive DC bus, and a third converter switch configured to couple the second inductor to the negative DC bus, wherein the UPS is voltage-frequency independent.

AC switch PFC with integrated charger and DC-DC for online UPS systems

A battery-charging system configured to charge a battery of a device to a nominal voltage includes a load-detection circuit, memory storing controller-executable instructions, and a controller configured to execute the instructions, which cause the controller to detect a load coupled to the battery above a first threshold load using the load-detection circuit, and control the battery-charging circuit to charge the battery to a high voltage in response to detecting the load above the first threshold load, wherein the high voltage is above the nominal voltage. The controller can be configured to execute other instructions, such as outputting a notification that the battery is being charged to a high voltage and/or controlling the battery-charging circuit to discharge the battery in response to detecting a reduced load or a user command.
