2. Introduction
The SKYPER 42 LJ core constitutes an interface between IGBT modules and the controller. This core has two
driver channels which can be used for half bridges or as two independent driver channels. Driving, insulation
and protection functions are integrated in the driver. The primary and secondary side circuits are integrated in
SEMIKRON’s new ASIC chipset for high reliability. SKYPER 42 LJ R is developed for systems up to 400kW.

Please consider higher tolerances of connector position according to IPC A 610


For integrating the SKYPER 42 LJ R driver core into an inverter system an adaptor board has to be built.
The adapter board builds the interface between the driver core and the IGBT module. The driver can be
soldered on the adapter board or plugged into connectors.
SEMIKRON offers adaptor boards for SKiM 63/93 modules. For customer specific adaptor boards please
contact your responsible sales for further information.
Fig. 4: Adapter board for SKIM 93
Adapter board with DC link measurement and
temperature shutdown feature. The adapter board
connects three SKYPER 42 LJ R with one SKiM63/93 GD
module. SEMIKRON’s adapter boards are sent out
without gate resistors or VCE components. These can be
modified according to application requirements. For
higher volumes SEMIKRON offers a standard population
service of these components.

Soldering Hints




The temperature of the solder must not exceed 260°C, and solder time must not exceed 10 seconds.
The ambient temperature must not exceed the specified maximum storage temperature of the driver.
The solder joints should be in accordance to IPC A 610 Revision D (or later) - Class 3 (Acceptability
of Electronic Assemblies) to ensure an optimal connection between driver core and printed circuit
board.
The driver is not suited for hot air reflow or infrared reflow processes.

4.3 Power supply - primary
Requirements of the auxiliary power supply
Power rating of external power supply
>15W
The same power supply can be used for SKYPER 32 and SKYPER 42. Do not apply switching signals during
power on reset.
4.4 Gate driver signals - primary
The inputs have a Schmitt Trigger characteristic and a positive / active high logic (input HIGH = IGBT on; input
LOW = IGBT off).
It is mandatory to use circuits which switch active to +15V and 0V. The duty cycle of the driver can be adjusted
between 0 – 100%. It is not permitted to apply switching pulses shorter than 1µs.
Fig. 8: TOP / BOT Input
A capacitor is connected to the input to obtain high
noise immunity. This capacitor can cause for
current limited line drivers a little delay of few ns,
which can be neglected. The capacitors have to be
placed as close as possible to the driver interface.
In addition one can add a series resistor for even
higher robustness with the consequence of a longer
delay time.

Any error detected will force PRIM_nERROR_OUT into low state (low active). Switching pulses from the
controller will be ignored for 30µs. Connected and switched off IGBTs remain off. For detailed error
management please see chapter 6.1 Failure management.
The output PRIM_nERROR_OUT is an open collector output. For the error evaluation an external pull-upresistor is necessary. The error output is not short circuit proof.

5. Protection features
5.1 Failure management
The SKYPER 42 LJ detects under voltage situation on primary and secondary side, short circuits and errors
from the external protection circuits like over temperature or over current. Any error detected will force the
output PRIM_nERROR_OUT into low state. The IGBTs will be switched off (IGBT driving signals set to LOW).
The input side switching signals of the driver will be ignored. The driver is reset after 30µs with the following
conditions:
 No error root cause for 30µs (Reaction on customer side has to be done within that time)
 Switching inputs low for 9µs (also within the 30µs)
Following failures are indicated by the failure output
 Under supply voltage situation on primary and secondary side
 Short circuit in the IGBT bridge
 Generic failure input of the secondary side failure input: Over temperature, over current
 Primary side error input

SKYPER 42 LJ R
The failure management of SKYPER 42 LJ R can be modified according to the application. SKYPER 42LJ
offers the possibility I.e. for MLI topologies to indicate error conditions without switch off. The driver sends an
error signal over a separated transformer to ensure safe and fast error indication in each switching condition.
The switch off procedure can than done by the controller according to each application.

5.2 Dead time generation (Interlock TOP / BOT ) adjustable
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. The highest dead time dominates.
Example:
Controller > driver
Controller < driver
Controller no dead time

It is possible to control the driver with one switching signal and its inverted signal. No error signal will be
generated when signals are overlapped.

5.3 Short pulse suppression
This driver circuit suppresses short turn-on and off-pulses of incoming signals. This way the IGBTs are
protected against spurious noise as they can occur due to bursts on the signal lines. Short or high noise pulses
don’t affect the driver on the controller side. The filter time can be set up by the customer. When using the
digital filter the tolerances are very low over the hole temperature range. The analogue setting can be chosen
for ambitious applications like MRI which require very low jitter values. The delay times are different depending
on the setting.

5.4 Dynamic short circuit protection by VCEsat monitoring ( DSCP )
The DSCP monitors the collector-emitter voltage VCE of the IGBT during its on-state.
The reference voltage VCEref may dynamically be adapted to the IGBTs switching behaviour. Immediately after
turn-on of the IGBT, a higher value is effective than in steady state. VCEstat is the steady-state value of VCEref and
is adjusted to the required maximum value for each IGBT by an external resistor RCE. It may not exceed 10V.
The time constant for the delay (exponential shape) of V CEref may be controlled by an external capacitor CCE. It
controls the blanking time tbl which passes after turn-on of the IGBT before the VCEsat monitoring is activated.

After tbl has passed, the VCE monitoring will be triggered as soon as VCE > VCEref and will turn off the IGBT.

5.5 Soft Off
In the event of short circuit, the SoftOff feature increases the resistance in series with RGoff and slows down the
turn-off speed of the IGBT. The reduced di/dt reduces the voltage spike above the collector emitter in the short
circuit case. The soft turn-off time can be adjusted by connection an external resistor RSoftOff .
Connection SEC_TOP_IGBT_SOFTOFF
The SoftOff resistor should be calculated 10 times
as high as the standard off resistor.

The SKYPER 42 LJ does offer an over
voltage detection feature. The SKYPER 42
LJ blocks switch off signals from the
controller as long as an overvoltage on the
