A DRSSTC with little load behaves much as a regular Tesla coil. Energy goes first from the power supply to the secondary coil and then flows back. If the driver is stopped at the peak of the secondary voltage the energy returns through the diodes. If the driver continues to operate the energy returns through the transistors, if they conduct in both directions, or through the diodes anyway. With the driver continuing to switch the same cycle repeats. When the load is not light the situation changes gradually from partial notches with energy flowing mostly to the load to unidirectional power transfer. The last situation does not occur in a regular coil, because all the energy comes from the initial energy in the primary capacitor. In a DRSSTC the driver can provide energy at any moment and there is no need to trap energy in the secondary. What is important is to not keep unused energy in the primary circuit, but transfer it to the secondary as fast as possible. I have a program that can simulate (and design) a DRSSTC at http://www.coe.ufrj.br/%7Eacmq/programs/drsstcd.zip.Hello, As we all (should) know, when the spark gap fires energy can transfer from the primary to secondary coil, and vice versa, which is why first notch quenching is important. However, how does that concept transfer over to solid state coils? I am no expert here, and I realize there are quite a few variations and styles of solid state drivers...but I believe the most highly developed version is the H bridge DRSSTC, correct? And they have a free wheeling diode, which serves to prevent damage to the MOSFET/IGBT, but does it also keep energy trapped on the secondary side as well? Else how is energy trapped in the secondary? Thanks, ~Dan (still a lover a spark gaps) Kansas City area
