Open State Resistances | Resistances of phases A, B and C of the switch in open state (ohm) |
---|---|
Closed State Resistances | Resistances of phases A, B and C of the switch in the closed state (ohm) |
Holding Current | Current threshold value below which the valve is automatically blocked. Not relevant for the ideal switch (A) |
Snubber Capacitance | The capacitance of the RC snubber branch in parallel with the valve (F) |
Snubber Resistance | The resistance of the RC snubber branch in parallel with the valve (ohm) |
Forward Break Overvoltage | The highest value of overvoltage across a blocked valve. Relevant only for the diode, the GTO and the thyristor (V) |
Reverse Break Overvoltage | The highest value of over-voltage across a valve. Relevant only for the diode, the thyristor and the GTO (V) |
Turn-off Time | The lowest time interval during which the voltage across the valve must stay negative to avoid the valve being fired again when the forward voltage turns positive. Relevant only for thyristor (s) |
GTO Maximum Breakable Current | Maximal value of the GTO current that can be turned off by the GTO turn off command. Relevant only for the GTO (A) |
Forward Voltage Drop | Minimal forward voltage for which valve firing is possible. Relevant only for the diode, the thyristor and the GTO (V) |
