SKYPER™ 32PRO -
Dead Time generation (Interlock TOP / BOT) adjustable (DT)
The DT circuit prevents, that TOP and BOT IGBT of one half bridge are switched on at the same time (shoot
through). The dead time is not added to a dead time given by the controller. Thus the total dead time is the
maximum of "built in dead time" and "controller dead time". It is possible to control the driver with one switching
signal and its inverted signal.
The dead time can be adjusted and the locking function may be neutralized as shown in the following table.

Adjustment of Dead time / Neutralizing Locking Functions
Please note:
A HIGH signal @ PRIM_HALT_IN does not generate a HIGH signal @ PRIM_HOLD_OUT. After LOW
signal @ PRIM_HALT_IN the gate driver is enable do operate.
Please note:
No error message will be generated when overlap of switching signals occurs.

pattern. Moreover the switching time of the IGBT chip
has to be taken into account (not shown in the pulse
pattern).
In case both channel inputs (PRIM_TOP_IN and
PRIM_BOT_IN) are at high level, the IGBTs will be
turned off.
If only one channel is switching, there will be no interlock
dead time.
