MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511116643 A) filed by Indian Institute Of Technology, Jodhpur, Rajasthan, on Nov. 25, 2025, for 'system and method for implementing a frequency-domain digital twin framework for a two-stage single-phase grid-connected solar photovoltaic (spv) inverter.'
Inventor(s) include Kumar, Arun; and Kumar, Nishant.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to a system (100) for implementing a frequency-domain digital twin framework for a two-stage single-phase grid-connected solar photovoltaic (SPV) inverter. The system includes a photovoltaic (PV) array (102) for generating direct current (DC) power, a boost DC-DC converter (104) for regulating output and performing maximum power point tracking (MPPT), and a DC-link capacitor (106) for energy buffering. A single-phase inverter (108) converts the DC voltage into alternating current (AC) for grid injection, while a ripple filter (110) reduces harmonic distortion. A sensing subsystem (112) measures electrical parameters from both the physical and digital twin systems. A spectral engine (114) models the SPV system in the frequency domain, and a controller (116) dynamically estimates parameters, synchronizes the digital twin with real-time operation, and performs predictive diagnostics to ensure stability, reliability, and grid compliance with sub-millisecond latency and high accuracy."
