Body

Hi Ole
 Also it is good practice to put a very fast suitable diode over each of the back to back mosfets, stretching from the source, going to the drain.
 If no diode there on each mosfet then the back to back diodes will tend to turn on "individually" rather than allowing AC flow to flow freely through the back to back bidirectionally connected diodes.
 This with peak coil shorting is important as during the switch closure is when the hyper AC ringing occurs and to keep it sustaining when switch is closed you need those diodes from source to drain.
