Frågan är relaterad till man andra fråga om halvbryggor. Om man triggar båda tyristorerna med samma puls så kommer den ena att få en puls då den är backförspänd. På vilket sett kan det vara att problem enligt citatet ovan?You also should be careful to avoid gate current during the quadrant
where the SCR has reverse voltage applied to it.
edit:
Menar de månne
(http://www.onsemi.com/pub_link/Collateral/HBD855-D.PDFWhen triggering an SCR with a dc current, excess
leakage in the reverse direction normally occurs if the
trigger signal is maintained during the reverse blocking
phase of the anode voltage. This happens because the
SCR operates like a remote base transistor having a gain
which is generally about 0.5. When high gate drive
currents are used, substantial dissipation could occur in
the SCR or a significant current could flow in the load;
therefore, some means usually must be provided to
remove the gate signal during the reverse blocking phase.

Men då borde det sakna betydelse här då jag triggar med en puls?
