MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202631075429 A) filed by Indian Institute Of Engineering Science And Technology on June 18, 2026, for A Controller And Method For Controlling A Multilevel Voltage Source Inverter.
Inventors include Paul, Ranajay; Dhara, Debanjan; Dalapati, Suvarun; and Ganguly, Debjani.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The present disclosure relates to a controller (200) for a multilevel voltage source inverter. The controller (200) includes an input interface (204) to receive a reference voltage (206) and a Direct Current (DC) bus voltage (208), a mode determination circuit (210) to determine an operating mode, a reference generation circuit (212) to generate reference signal, a pulse width modulation (PWM) generation circuit (214) to generate a PWM signal during a switching period and a switching control circuit (216) to generate gate signals for semiconductor switches (SW1-SW8). The controller (200) determines the operating mode from the received reference voltage (206) relative to the DC bus voltage (208), generates the reference signal and the PWM signal during the switching period and generates the gate signals to control switching of the semiconductor switches (SW1-SW18), such that a duty ratio of the PWM signal is corrected within the switching period.
