Fig. 5 TIMING CHART OF THE DIP-IPM PROTECTIVE FUNCTIONS

[A] Short-Circuit Protection (Lower-arms only with the external shunt resistor and CR filter)

a1. Normal operation : IGBT ON and carrying current.

a2. Short circuit current detection (SC trigger).

a3. IGBT gate hard interruption.

a4. IGBT turns OFF.

a5. FO timer operation starts : The pulse width of the FO signal is set by the external capacitor CFO.

a6. Input “L” : IGBT OFF.

a7. Input “H” : IGBT ON.

a8. IGBT OFF in spite of input “H”.

[B] Under-Voltage Protection (Lower-arm, UVD)

b1. Control supply voltage rises : After the voltage level reaches UVDr, the circuits start to operate when next input is applied.

b2. Normal operation : IGBT ON and carrying current.

b3. Under voltage trip (UVDt).

b4. IGBT OFF in spite of control input condition.

b5. FO operation starts.

b6. Under voltage reset (UVDr).

b7. Normal operation : IGBT ON and carrying current.
