SSTC, Modes and soft switching

Hi all,

As described in my message subject: Mode splitting.  By offsetting the 
primary and secondary frequencies one of the modes of the split fundamental 
mode disappears.

This may be a useful configuration for an SSTC because both the initial 
transient and the steady state current may be in phase with the drive 
voltage if its at the frequency of the remaining mode.  Hence soft 
switching even at the start of a burst may be achievable (assuming no break 
out)

I have not yet done the transfer function analysis or transient analysis. 
Which I will try to do unless someone can point out a problem with this 
approach or error in my thinking.
As always it may well have already been considered.

I believe it has been suggested that from observation of the performance 
that a system with an offset works better. Has anyone quantified the offset 
and or got a frequency response of such a system?

Comments anyone?

Bob
