<p>The invention relates to a converter provided with a resonant circuit (16), in which converter the resonant circuit comprises means (31) for detecting a zero current condition in the auxiliary valve. Said means (31) is adapted to send to the control device (24) of the converter signals indicating a prevailing zero current condition in the auxiliary valve, and the control device (24) is adpated to allow a turn-off of a semiconductor component (20a, 20b) of turn-off type of the auxiliary valve only after the receipt by the control device (24) 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.</p> |
