12) The maximum dynamic voltage between auxiliary emitters of parallel-connected drivers due to
asymmetrical operation at turn-on and turn-off must be limited to the given value.
13) Maximum allowed rate of change of auxiliary emitter voltage of parallel connected drivers. This
specification guarantees that the drive information will be transferred reliably even with high rate of
change of auxiliary em itter voltages (asymmetrical operation).
14) Dy namic v olta ges between auxiliary emitters of para llel connecte d drivers at turn-on and t urn -off le ad
to equa lizing curr ents over the X2 or X3 bus. The pe ak and RMS values of the re sulting curr ent must
be limited to the given value.
15) Undervoltage monitoring of the secondary-side supply voltage (Viso to Vee and Vee to COM which
correspond with the approximate turn-on and turn-off gate-emitter voltages). If the corresponding
voltage drops below this limit on 1SP033 5x2Mx (ma sters) , all para lleled IGBTs (master a nd slaves) are
switched off and a fault is transmitted to the status output. If the correspondi ng voltage drops be low
this limit on 1SP0335D2Sx (slaves), the corresponding IGBT is switched off. If the IGBT was turned
on, a fault will be generated by the gate-monitoring function on the master which will turn off all
paralleled IGBT after the corre sp onding delay.
16) The mean value VGE,mean of all gate voltages (master and all slaves) is filtered and compared to the
given values at turn-on and turn-off. If the specified values are exceeded (V GE,mean<VGE,on,min at turn-
on resp. VGE,mean>VGE,off,max at turn-off) after the given filter delay, the driver turns off all parallel-
connected IGBTs and a fault is transmitted to the status output.
17) A dynamic Vce protection is implemented on the driver. The maximum allowed Vce voltage at turn-on
is dynamically adjusted in order to better fit t o the IGBT characteristics at turn-on. At the end of the
turn-on process the given s tatic value applies.
18) The resulting pulse widt h of the dire ct output of the ga te drive unit for short-ci rcuit t ype I (excl uding
the delay of the gate resistors) is the sum of the response time plus the dela y to IGBT turn-off.
19) The turn-off event of the IGBT is delayed by the specified time after the response time.
20) Including the delay of the external fiber-optic links (cable length: 1m). Measured from the transition
of the t urn-on or turn-o ff command at the optical transmitter on the host controller side to the direct
output of the gate drive unit (excluding the dela y of the gate resistors).
21) Output rise and fall times are measured between 10% and 90% of the nominal output swing. The
values are given for the driver side of the gate resistors with 2Ω/1uF load. The time constant of the
output load in conjunction with the present gate resistors leads to an additional delay at their load
side.
22) Delay of external fiber-optic links. Measured from the driver secondary side (ASIC output) to the
optical receiver on the host controller.
23) Measured on the host side. The fault status on the secondary side is automatically reset after the
specified time.
24) Including the delay of the external fiber-optic links. Measured from the transition of the turn-on or
turn-off command at the optical transmitter on the host controller side to the transition of the
acknowledge signal at the optical r eceiver on the host controller sid e.
25) The gate resistors can be leaded or surface mounted. CONCEPT reserves the right to determine which
type will be used. Typically, higher quantit ies will be produced with SM D resistors a nd small quantities
with leaded resistors.
26) The driver s upply voltag e VDC is split into tw o distinct voltages on the driver. The first one is the turn-
on voltage which is regulated at about 15V. The difference between VDC and the turn-on voltage is
the turn-off voltage which is not regulated and mainly dependent on the d river input voltage VDC.
27) The fault status is set as long as the gate monitoring fault is present. The given value applies if the
driver goes from the “off state” to the “on state” and the gate-emitter voltage of one or more parallel
connected drivers does not turn on. If the driver goes from the “on state” to the “off state” and the
gate-emitter voltage of one or more parallel connected drivers does not turn off, the fault status is
applied as long as the ga te monitoring fault is prese nt.
