7.3 Short-Circuit Protection

voltage exceeds the V
the lower arm IGBTs are turned off. Typically the maximum short circuit current magnitude is gate voltage
dependant. A higher gate voltage results in a larger short circuit current. In order to avoid this potential
problem, the maximum short circuit trip level is generally set to below 1.7times the nominal rated collector
current. The LVIC short circuit protection-timing chart is shown in Figure 7.3.

(with the external shunt resistance and RC connection)
c1 : Normal operation: IGBT ON and carrying current.
c2 : Short circuit current detection (SC trigger).
c3 : Hard IGBT gate interrupt.
c4 : IGBT turns OFF softly.
c5 : Fault output timer operation starts:
c6 : Input “L” : IGBT OFF state.
c7 : Input “H”: IGBT ON state, but during the active period of fault output the IGBT doesn’t turn ON.
c8 : IGBT OFF state
The LVIC has a built-in short circuit function. This IC monitors the voltage to the C
The pulse width of the fault output signal is set by the external capacitor CFO.
