Hopefully you saw my attempt of a universal driver. With your help I'd be happy to upgrade this to something everyone can take advantage of. Probably use some sort of pluggable MOSFET arrangement for driving whatever load is needed. May need to think about how best to drive something like SIC MOSFETs that pull the gate below zero.
Good day All Couldn't resist posting some pic.s of my SiC_Pack. It is designed to pulse Six Cree C2M0080120D mosfets in Series. This is the equivalent of a 7kV2 switch, with complete galvanic isolation (GDT with 12kV2 30awg magnet wire). Still in testing phase, but working extremely well. Have attached some scope shots as well. This was primarily designed for nano-second pulsing, but as you can see it will (with the appropriate GDT) produce a clean 50% duty cycle as well (30ns rise/fall times at the gate). Generally I can obtain <1ns skew between channels (mosfets) at anywhere from a 50kHz to over 2MHz range. I am currently using an Arduino based signal generator which interfaces with a hardware hacked AD9850 dds. The hardware hack allows for control of the duty cycle of the AD9850 dds by the arduino as well. The gate signal floats a -4 to +20 volt signal. The positive offset is adjustable on the fly and the negative offset is part of the design (must change out components to modify). This was designed as part of another project which requires HV nano-second pulses. take care, peace lost_bro
