Patent number: 11936238Abstract: An uninterruptible power apparatus is coupled between a power grid and a load. The uninterruptible power apparatus includes a bypass path, a power conversion module, and a control module. The bypass path is coupled to the power grid through a grid terminal, and coupled to the load through a load terminal. The control module turns off a first thyristor and a second thyristor by injecting a second voltage into the load terminal during a forced commutation period. The control module calculates a magnetic flux offset amount based on an error amount between the second voltage and a voltage command, and provides a compensation command in response to the magnetic flux offset amount. The control module controls the DC/AC conversion circuit to provide a third voltage to the load terminal based on the compensation command and the voltage command.Type: GrantFiled: June 15, 2022Date of Patent: March 19, 2024Assignee: DELTA ELECTRONICS, INC.Inventors: Hsin-Chih Chen, Hung-Chieh Lin, Chao-Lung Kuo, Yi-Ping Hsieh, Chien-Shien Lee
