  • Integrated magnetic module
    Patent number: 9490057
    Abstract: An integrated magnetic module includes a first auxiliary circuit board, a second auxiliary circuit board, a first transformer, a second transformer and at least one inductor. The second auxiliary circuit board and the first auxiliary circuit board are arranged side by side. The first transformer is disposed on the first auxiliary circuit board. The second transformer is disposed on the second auxiliary circuit board. The at least one inductor is arranged between the first transformer and second transformer, and electrically connected with the first auxiliary circuit board and the second auxiliary circuit board.

  • Electronic fuse apparatus and method of operating the same
    Patent number: 9030794
    Abstract: An electronic fuse apparatus is connected between a power side and a system side. The electronic fuse apparatus mainly includes an electronic fuse, a short-circuit protection switch, a current-sensing module, and a digital control module. The current-sensing module detects an operating current which flows from the power side to the system side. The digital control module generates a control signal to control the electronic fuse. When the current-sensing module detects that the operating current is over-current, the digital control module generates the high-level control signal to turn off the electronic fuse, thus providing an over-current protection. When a short-circuit fault occurs at the system side, the short-circuit protection switch is turned on to turn off the electronic fuse, thus providing a short-circuit protection.
