Circuit Analysis: DRSSTC

["Tesla list" <tesla@xxxxxxxxxx>]

Hi All,

Is their a primary circuit schematic and waveform set that defines 
the quintessential DRSSTC?  Searches of pupman archives seem to hint 
at resonant primary switching, with relatively long (>>6 cycles) 
dwell times -- similiar in nature to a resonant-mode converter.
I had originally thought that the DRSSTC uses a full-wave bridge, in 
a hard switch-mode approach (square primary voltage waves, ramped 
primary current waves, sinusoidal secondary V&I waves.)

I'm currently running a batch of simulations in Simplorer, and wanted 
to further characterize the relative efficiencies and drawbacks of 
various primary switching topologies.

Best Regards,
Greg
