#157328 - good luck Responding to: ???'s previous message |
I have used many 'industrial' inverters and all use 100 times more processing power than a '51 will provide. good luck.
The IGBT module is 6MBI4500-120 with 15A and 600V they will blow, you need 4 times the RMS (experience, do not ask for why) What can be the PCB design consideration for High voltage circuits. Separation, but that is the least of your worries. What will get you is that the nanoHenrys (nanoHenries?) that traces have will cause ringing to kingdom come. I guess that a truly professional inverter PCB layout person with thousands of dollars of test equipment will go through 10-25 layouts before getting it right. Erik |
