摘要 |
The invention relates to a converter provided with a resonant circuit, in which converter the resonant circuit comprises means for detecting a zero current condition in the auxiliary valve. The means is adapted to send to the control device of the converter signals indicating a prevailing zero current condition in the auxiliary valve, and the control device is adapted to allow a turn-off of a semiconductor component of turn-off type of the auxiliary valve only after the receipt by the control device of a signal indicating a prevailing zero current condition in the auxiliary valve. The invention also relates to a method for controlling such a converter. |
