MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202421021448 A) filed by Varroc Engineering Limited, Aurangabad, Maharashtra, on March 20, 2024, for 'a system and method for establishing power supply in a three-phase rectifier circuit in a battery-less state of a vehicle.'
Inventor(s) include Madathil Krishna Pratap; and Shriram Shubham Venkatesh.
The application for the patent was published on Sept. 26, under issue no. 39/2025.
According to the abstract released by the Intellectual Property India: "A system and method for establishing power supply in a three-phase rectifier circuit in a battery-less state of a vehicle is provided. The circuit (115) includes switching elements (301a), (301b), and (301c) connected to each phase of a generator (101), a series switch (303) configured to establish an electrical connection with the main power supply, and a switching 10 circuit (307) to control the series switch (303). The series switch (303) may be a P-channel MOSFET, and the switching elements can be MOSFETs. A microcontroller (309) is included to control the switching circuit (307). The circuit (115) may also incorporate a gate driver (305) to drive the switching elements (301a), (301b), (301c) and establish the necessary power supply connection. A method (400) for establishing the power supply involves detecting the 15 power supply during a kickstart phase, comparing the sensed voltage with required thresholds, and activating the switching elements to complete the circuit, ensuring proper voltage levels before disconnecting the battery-less circuit."
