Latest Patents

Sungjae Ohn holds a patent for "Three-phase, three-level inverters and methods for performing soft switching with phase synchronization." This invention discloses a three-phase, N-level inverter and method that includes a circuit topology comprising first, second, and third sets of switches, along with first, second, and third inductors. Each switch features at least first, second, and third terminals, with the first terminals serving as control terminals. The first terminals of the inductors are electrically coupled to the respective sets of switches. A current controller executes a control algorithm that generates gating signals to control the switches, enabling zero voltage switching while maintaining synchronization across the three phases of the inverter. This innovative approach enhances the efficiency and reliability of inverter systems.
