IGBT DRIVERS : PrimePACK Slave Series
Plug & Play Driver for PrimePACK Slave Series

In any IGBT parallel system the on/off timing of the IGBT is critical. Any difference can result in initial current mismatch in the IGBTs, and that creates additional stresses on the IGBTs that can lead to premature failure. In a parallel design that uses all masters, there are more components in the path from the host gate trigger to the IGBT gate drive. With the Master Slave solution, a single master generates a pre gate drive signal that is only one step back from the final gate drive signal. This means there are less components in that path resulting in minimal timing mismatch in production.

The Master has been designed to have sufficient output wattage to supply both it and the slave. This makes each IGBT drive have identical voltage supplies further reducing mismatch and at the same time reducing cost.
The Master solution is not impacted by the inductance of the pre-gate driver signal from the master to the slave since this pre-gate drive signal is less than 0.5 amps. At this low level the stray inductance of the leads from the Master to the Slave will not have any impact. |
