Fig. 8 TIMING CHART OF THE PROTECTIVE FUNCTIONS
[A] Short-Circuit Protection (N-side only with the external shunt resistor and RC filter)
a1. Normal operation : IGBT ON and carrying current.
a2. Short circuit is detected (SC trigger).
a3. All N-side IGBTs’ gates are hard interrupted.
a4. All N-side IGBTs turn OFF.
a5. FO is output (tFO(min) = 20
s).
a6. Input “L”.
a7. Input “H”. But IGBT is still OFF state during outputting FO.
a8. IGBT turns ON when L
→H signal is input after FO is reset.
[B] Under-Voltage Protection (N-side, UVD)
b1. Control supply voltage VD rises : After VD level rises over under voltage reset level (UVDr), the circuits start to operate when next input
is applied.
b2. Normal operation : IGBT ON and carrying current.
b3. VD level dips to under voltage trip level. (UVDt).
b4. All N-side IGBTs turn OFF in spite of control input condition.
b5. FO is output. (tFO
≥ 20s and FO outputs continuously during UV period).
b6. VD level rises over UVDr.
b7. Normal operation : IGBT ON and carrying current.
