CURRENT ABNORMALITY PROTECTIVE FUNCTIONS
ARM-SHOOT-THROUGH INTER-LOCK PROTECTIVE FUNCTION
Protection is achieved by monitoring and filtering the N-side DC-Bus
current. When a current trip-level is exceeded all the N-side IGBTs are
intercepted (turned OFF) and a fault-signal is output. After the fault-sig-
nal output duration (1.8msec (typ.)@25
°C), the interception is Reset at
the following OFF input signal level (more than 4.0V).

Description:
(1) During the ON-State of either of the upper-arm or the lower-arm IGBT, the inter-lock protection circuit blocks any erroneous ON pulses (re-
sulting from input noise) from triggering the other arm IGBT and thus it prevents the arm-shoot-through situation.
(2) When two ON-signals are received for both the upper and the lower arms, the signal received first will be passed to the IGBT and the sec-
ond signal will be blocked. The second signal will be passed to its corresponding IGBT immediately after the first signal is OFF.
Note: This protective function provides no fault signaling output. The Dead-Time has to be set using the micro-controller (CPU).
b1. N-side normal ON-signal
N-side IGBT gate turns ON.
b2. Simultaneous ON-signals
P-side IGBT gate remains OFF.
b3. N-side receives OFF-signal
N-side IGBT gate turns OFF.
b4. Immediately after (b3)
P-side IGBT gate turns ON.
Operation:
a1. P-side normal ON-signal
P-side IGBT gate turns ON.
a2. N-side erroneous ON-signal
N-side IGBT gate remains OFF.
a3. While P-side ON-signal remains
P-side IGBT gate remains ON.
a4. N-side normal ON-signal
N-side IGBT gate turns ON.
