Continuing on the 'Salty Citrus' replication:

This is the first test of the SiC_Pack_Driver_v1 pcb.

After extensive testing with the magnetics of the first hand made SiC_driver board, it became apparent that in order to reach the Nano-second precision required for this project, a *real* pcb must be produced.

So we have the *SiC_Pack_Driver_v1* pcb.

As can be seen, (only testing one of the six channels of the pcb) the rise and fall times are respectable for a high speed magnetics based / isolated SiC Mosfet driver. Actually we are at the *spec sheet* limits for the CREE C2M0080120 SiC mosfet. Of course a digital based driver setup could easily half these speeds, but being old school I opted for the magnetics based isolation as it is pretty much bullet-proof.

The single channel was tested to a frequency of over 1.4MHz @ pulse width of 76-78ns. The rise / fall times are 24ns / 20ns approx. with test toroid. Finished pcb will have slightly faster rise / fall times do to shorter lead length on installed toroids.

Further videos will be posted as the WIP progresses............
