MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202641012426 A) filed by National Institute Of Technology, Mangaluru, Karnataka, on Feb. 5, for 'a virtually grounded h-9 five-level switched boost capacitor transformerless inverter.'
Inventor(s) include Md Sartaj Ahmed; Ravi Raushan; and Md Waseem Ahmad.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "A Virtually Grounded, Switched-Capacitor based H-9 Five-Level Transformerless Inverter 5 A Virtually Grounded, Switched-Capacitor based H-9 Five-Level Transformerless Inverter (100) is disclosed. Inverter (100) includes Direct Current (DC) source, SB module (102), SC unit (104), conventional H-bridge, and virtual capacitor unit (106). SB module (104) includes boost inductor (Lin), one power switch (S1), and one diode (D). SC unit includes two capacitors (C1 and C2), three 10 switches (S2, S3, and S4). Virtual capacitor unit includes capacitors C01 and C02 (C01 = C02) is virtually grounded. This unit provides low-impedance path for high-frequency current components, thereby bypassing them from the ground path and effectively reducing the leakage current flowing through the ground. Switches S3 and S5, along with capacitors C1 and C2, control output voltage level, while switches S6 to S9 determine output voltage polarity. Inverter regulates 15 voltage and maintains a desired voltage level while minimizing a ripple current of the capacitors in the SC unit."
