MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202541060880 A) filed by Srm University, Amaravati, Andhra Pradesh, on June 25, for 'system and method for controlling a magnetically coupled single-input dual-output (mc-do) dcdc converter.'
Inventor(s) include Tousif Khan Nizami; Arghya Chakravarty; and Vijayasri Averneni.
The application for the patent was published on July 11, under issue no. 28/2025.
According to the abstract released by the Intellectual Property India: "The present disclosure envisages a system (100) and a method (900) for controlling a magnetically coupled single-input dual-output (MC-DO) DC-DC converter (110). The system (100) comprises a decoupled capacitor current ripple (DCCR) control module (102) to receive a respective capacitor current ripple feedback signal and process the ripple feedback signals to independently regulate each output voltage by isolating ripple components attributable to magnetic coupling for generating decoupled voltage control signals, a dual-output current modulator (104) to receive the decoupled voltage control signals as input and dynamically allocate output current to each output port of the MC-DO DC-DC converter (110) based on real-time decoupled ripple characteristics for minimizing cross-coupling effects, a cascade control module (106) to receive output current modulation signals. The cascade control module (106) has an inner current loop to stabilize the output current via capacitor current feedback, and an outer voltage loop configured to generate a compensator control signal via a Type-II compensator."
