MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202621018332 A) filed by Visvesvaraya National Institute Of Technology, Nagpur, Maharashtra, on Feb. 18, for 'a laboratory-grade analog solar pv emulator system for academic and research-based solar energy studies.'
Inventor(s) include Ballal, Makarand Sudhakar; Adkine, Gajanan U; and Verma, Shivpal R.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure provides an analog solar photovoltaic (PV) emulator system comprising a plurality of emulator modules, each configured to independently generate a direct current (DC) output simulating a single PV panel. The system comprises analog control components configured to emulate PV panel behaviors and a configurable interconnection arrangement enabling manual interconnection of output terminals in series-parallel array configurations. Each emulator module comprises a dimmerstat to vary input alternating current (AC) voltage emulating irradiance changes, a regulator to adjust AC voltage level emulating temperature-dependent voltage drops, a potentiometer to modulate output current emulating partial shading or panel degradation, and a double-pole double-throw (DPDT) switch to selectively break a circuit path emulating bypass diode failure. Each module further comprises a step-down transformer, bridge rectifier, capacitor filter, and current limiting resistor."
