Application and Handling Instructions

Please provide for static discharge protection during handling. As long as the hybrid driver is not completely assembled,

the input terminals have to be short-circuited. Persons working with devices have to wear a grounded bracelet. Any

synthetic floor coverings must not be statically chargeable. Even during transportation the input terminals have to be

short-circuited using, for example, conductive rubber. Worktables have to be grounded. The same safety requirements

apply to MOSFET- and IGBT-modules.

Any parasitic inductances within the DC-link have to be minimised. Over-voltages may be absorbed by C- or RCD-

snubber networks between main terminals for PLUS and MINUS of the power module.

When first operating a newly developed circuit, SEMIKRON recommends to apply low collector voltage and load current

in the beginning and to increase these values gradually, observing the turn-off behaviour of the free-wheeling diode and

the turn-off voltage spikes generated across the IGBT. An oscillographic control will be necessary. Additionally, the case

temperature of the module has to be monitored. When the circuit works correctly under rated operation conditions,

short-circuit testing may be done, starting again with low collector voltage.

It is important to feed any errors back to the control circuit and to switch off the device immediately in failure events.

Repeated turn-on of the IGBT into a short circuit with a high frequency may destroy the device.

these inputs. Therefore, control signal over-voltages exceeding the above values have to be avoided.

The connecting leads between hybrid driver and the power module should be as short as possible (max. 20cm), the

driver leads should be twisted.

General Description

The Board 3s SKYPER

can be customized allowing adaptation and optimization to the used SEMiX

The switching characteristic of the IGBT can be influenced through user settings, e.g. changing turn-on and turn-off speed
