MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202511106336 A) filed by Indian Institute Of Technology (Banaras Hindu University), Varanasi, Uttar Pradesh, on Nov. 3, 2025, for 'a direct current (dc) charging architecture for reduced power processing in high power charging system.'
Inventor(s) include Warda Matin Khan; Rajeev Kumar Singh; and Ranjit Mahanty.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a direct current (dc) charging architecture (100) for reduced power processing in high power charging system that comprises an input DC bus (101), a battery (102) and a DC/DC converter (103). The input DC bus (101) receives power from a DC source. The DC/DC converter (103) is a resonant dual active bridge converter and connected in an input-parallel and output-series configuration between the input DC bus (101) and battery (102). The DC charging architecture (100) establish a two power transfer paths. The two power transfer paths have a first power path transfer and a second power path transfer. The first power path transfers through DC/DC converter (103) that processes a part of power and the second power path transfer through an ideally lossless series bypass path that transfer the bulk power directly to the battery (102), thereby achieving reduce power processing and enhanced conversion efficiency."
