MUMBAI, India, Sept. 28 -- Intellectual Property India has published a patent application (202521002725 A) filed by Aliasgar Parvez Shayer on January 12, 2025, for Electrical Power System And Method For Single-Phase Traction Load Supply By Balancing Three-Phase Power Source.
Inventor includes Aliasgar Parvez Shayer.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: The invention relates to an electrical power system (100) and method for supplying single-phase traction loads (109) by balancing a three-phase power source (106). The system (100) comprises a multi-winding three-phase transformer (102), a power electronics converter (103), a coupling element (104), an isolation transformer (105), voltage sensors (107), current sensors (108), and a controller (700). The converter (103), connected in parallel with single-phase loads (109), redistributes active power among secondary phases to ensure balanced current draw. The coupling element (104), implemented as an inductor, LC, LCL, or TCLC module, enables reactive power support and harmonic mitigation. Vector-group configuration of transformer windings (111-113, 115-117) is selected to optimize converter control and phase angle alignment. The controller (700) dynamically regulates converter switching to maintain balanced operation, unity power factor, and improved power quality. Offering a cost-effective alternative to special transformer based traction substation for high-power single-phase applications. FIG. 1
