MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202617062025 A) filed by Tmeic Corporation on May 15, 2026, for Uninterruptible Power Supply Device.
Inventors include Imanishi, Ryogo; Yamamoto, Yushin; Kinoshita, Masahiro; and Nagano, Hirotaka.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: An uninterruptible power supply device (10) comprises: a converter (12) that converts AC power supplied from an AC power supply (1) into DC power and supplies the DC power to a DC bus (14); an inverter (18) that converts DC power received from the DC bus (14) into AC power and supplies the AC power to an AC transmission line (4); and a power storage device (3). The converter (12) includes a plurality of cascaded first converter cells. The inverter (18) includes a plurality of cascaded second converter cells. The power storage device (3) includes a plurality of power storage cells (3a) provided respectively corresponding to the plurality of first converter cells. Each of the plurality of first converter cells includes: a first input/output terminal and a second input/output terminal; a first bridge circuit including a plurality of semiconductor switching elements; a first capacitor connected to the first and second input/output terminals via the first bridge circuit; and a charge/discharge circuit. The charge/discharge circuit exchanges DC power between the first capacitor and the corresponding power storage cell.
