MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641042307 A) filed by Dr. C. Kumar; Dhanush M; Hari Prasath V; Kavi Bharathi M; and Kaviyarasan B, Coimbatore, Tamil Nadu, on April 2, for 'a switched capacitor based seven level single-phase inverter for voltage stress and harmonic distortion reduction.'
Inventor(s) include Dr. C. Kumar; Dhanush M; Hari Prasath V; Kavi Bharathi M; and Kaviyarasan B.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "This invention presents a switched-capacitor based seven-level single-phase inverter designed to reduce voltage stress on power switches and minimize harmonic distortion in output waveforms. Conventional two-level inverters experience higher stress and distortion, leading to reduced efficiency. The proposed system utilizes a multilevel inverter approach to generate output voltages closer to a sinusoidal waveform, thereby improving power quality. The architecture employs six switches and a single DC source to produce seven voltage levels while maintaining reduced circuit complexity. The switched-capacitor configuration enables efficient voltage balancing and eliminates the need for additional components. The system is validated through MATLAB simulation and hardware implementation, confirming its capability to produce stable and low-distortion AC output. Results demonstrate reduced total harmonic distortion and improved voltage distribution across switches. The inverter is suitable for applications such as renewable energy systems, industrial drives, and smart grid solutions, offering enhanced reliability, efficiency, and performance."
