Hi Herr Zapp,



Interesting questions, but how do they relate to answering the question Dave asked?

A few questions:?
?
1. How are you calculating the voltage requirements for the tank cap??
?
2. How large a multiplier are you using to define the capacitor's voltage margin (safety factor)??
?
3. What is the manufacturer's voltage rating for the IGBTs you will be using??
?
4. What is the calculated peak primary current??
?
Regards,?
Herr Zapp?

 Hi all,?
?
? I'm working on a fairly large DRSSTC and I find that an MMC adequate to 

?the task may be out of my financial reach. If I were to push the igbt 

?bridge to its limits I would require a cap rated at 20 kv at 0.5 mfd. 

?This begins to sound like pole pig territory. If anyone has a cap like 

?this that they would consider selling, or if they know of a resource that 

?I can pursue, please let me know.?
?
 Thanks,?
 Dave?
