POWER CONVERTER |
摘要 |
A power converter including a plurality of serially connected self-turn-off semiconductor elements, including a first control circuit for producing a plurality of control signals, and a plurality of second control circuits is connected to receive respective of the control signals to supply a non-conduction control signal to a respective of the self-turn-off semiconductor elements to turn off the respective semiconductor element. The power converter further includes a plurality of failure detectors and blocking circuits. Each of the failure detectors is connected to a respective of the self-turn-off semiconductor elements for detecting a fault thereof to produce a fault detection signal when the respective self-turn-off semiconductor elements has failed. Each of the blocking circuits is connected to the respective failure detector and to the first control circuit for blocking either the respective control signal or the respective non-conduction control signal based on the respective fault detection signal. |
