Re: [TCML] SISG success

Hi Phil,

Given your using a large quantity of boards, is it possible that timing 
regarding Sidac switching becomes more of an issue with more boards in 
series? Maybe higher voltage systems are more prone to breakdown? In 
other words, given say 20kV across the string of boards, if one board 
switches first, does this put the others at risk? The 20kV is then felt 
across the remaining boards (up until all the gates take over).

Regards,
Bart
