SKYPER™ 32

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-

snubbers 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.

Further application support

General Description

The SKYPER™ 32 core constitutes an interface between IGBT modules and the controller. This core is a half bridge driver.

Basic functions for driving, potential separation and protection are integrated in the driver. Thus it can be used to build up a

driver solution for IGBT modules.
