摘要： The invention relates to a method of operating an electronic valve in a converter, in particular a high power converter, wherein the valve comprises an electrically insulated control electrode and wherein the method comprises the steps: - an operating state of the converter and/or of the valve is/are monitored while the valve is open (e.g. resulting in logic time-dependent signals "High di/dt" and "Short circuit"), - if the operating state fulfils a first pre-defined criterion (indicated by "Short circuit = 1"), indicating that there is a short circuit which affects a current through the valve (18), a first process of de-charging the control electrode (G) is performed in order to close the valve (18) (the process starts after the right vertical dashed line), - if the operating state fulfils a second pre-defined criterion (indicated by "High di/dt = 1"), indicating that there may be a short circuit which affects a current through the valve (18), a second process of de-charging the control electrode (G) is per-formed before the first criterion is fulfilled or is performed before the first process is started (the process starts with the left vertical dashed line).

摘要： The invention relates to a method of operating an electronic valve (18), in particular an IGBT, wherein a process of changing a charging state of a control electrode (17) (in particular of an insulated gate) of the valve (18) is repeatedly performed in a like manner (controlled by units 10, 12). It is determined whether a specific operating state is reached at a predetermined point in time and with a corresponding determination result (unit 10 using information obtained by unit 16), the process of changing the charging state is adapted, if necessary.

摘要： The invention relates to an arrangement for operating an electronic valve (1) having an insulated gate (2), in particular for operating an Insulated Gate Bipolar Transistor. A measuring device (22) measures a time elapsed from an initiation of a first process, or elapsed from a characteristic point in time of the first process, wherein the first process is to be performed for switching on the valve (1). A driver device (17, 18) is adapted to perform at least a part of a second process, wherein the second process is to be performed for switching off the valve (1). A selecting device (24), which is connected to the measuring device (22) and to the driver device (13), is adapted to select an operation of the driver device (17, 18), wherein the selection depends on a measurement signal received from the measuring device (22).
