Method to eliminate errors in a rectifying circuit device |
摘要 |
<p>The method for fault repair in a current switching circuit (1) containing switches (2) consisting of multiple in-and-out switchable circuit modules (14) consisting of multiple parallel-connected switching chips (4) connected by connecting wires (3). In the event of a chip (4) being faulty, the connecting wires are destroyed by applying a fusing current. A power rectifier circuit containing multiphase d.c. supplied bridge has two switches per phase. In a first step all switches on each phase are turned on. In a second step in each phase the module (14) connected to the positive supply is energised, then the module connected to the negative supply is energised to test for defective modules.</p> |
