I'm using H-Bridge Driver Circuit Using Isolated Half-Bridge Drivers ( CN-0196 ) and i want to supply with 300V.
1- Can I ?and if not wich part i must modified
2- how much frequency limitte with 300V dc supplying
I'm afraid you cant - all of the power MOSFETs are only rated to 60V, as well as their anti-parallel diodes, the dc bus capacitors (which are all 50V rated), bootstrap diodes etc etc.
There is a three-phase inverter system platform based on the ADuM4223 gate drivers which will be available shortly and will be rated up to 800V. Watch this page!
