Abstract
An uninterruptible power supply device includes a rectifier module coupled to an electrical power grid, an inverter module coupled to the rectifier module, and a battery converter module. The rectifier module can process a higher amount of electric power as the designed electrical power provided by the inverter module to enable the uninterruptible power supply device to provide stabilization support to the electrical power grid, wherein the rectifier module comprises at least two rectifier submodules, each dimensioned to process an amount of electrical power according to a capability of the inverter module to process power. The rectifier module is configured to electrically couple the rectifier submodules selectable to process a higher amount of electric power as the inverter module to provide stabilization support to the electrical power grid.
