| r0d3z1:
thank you for the useful tips, my major issue is measuring the current on LFpack mosfet. Due to this package, rogowski coil and current transformer are not feasable. A low side SMD shunt is already in place for current control, however it is a normal one, not a dedicated one for high bandwith measurement. Than probably the parasitic inductance of SMD shunt could affect the measurement. I expect a voltage spike across low side shunt at low side mosfet turn-on. |
