METHOD AND DEVICE FOR CONTROLLING A POWER CONVERTER VALVE THAT CAN BE TURNED OFF AND HAS A NUMBER OF SERIES CIRCUITS AMOUNTING TO TWO OR MORE |
摘要 |
<p>Method and apparatus for controlling a turn-off power converter valve having at least two series connections. Each non-latching power semiconductor switch of this power converter valve has an active collector-emitter limiting circuit. When a rising edge of a drive signal that is provided arrives, a predetermined value of the reference limited voltage of the active collector-emitter limiting circuit is decreased to a low value and is increased to the predetermined value again during a turn-off operation. Using a switch-on command, it is possible to balance the voltage sharing on the non-latching power semiconductor switches of a turn-off power converter valve having at least two series connections.</p> |
