Re: Improved Model for a Primary Charging CKT

Hi,

Here is more detail of the problem.

The cap voltage consists of a series of terms:

vc = vss + vtr1 + vtr2 + vtr3 + .........etc

vss is the steady state response, vtr1, vtr2 etc are the transient responses
from each sg conduction.

vss is constant sin with a f equal to the supply f and an amplitude
determined by V R L and C
vtr's are damped cosines determined by the R L C frequency and  decay by
R/gap losses.
ie vss has the same f as the supply and vtr is the f of R L C.

vss is known.

vtr:
In the case of a srsg the phase is known but the amplitude is determined by
vss.
In the case of static sg the amplitude is known but the phase is determined
by the amplitude of vss.

Just solve the equation using the above and the fact vss goes to zero each
time the sg conducts.

Yep not a problem but you may have to think about it for a little while well
perhaps a long while.
