Is a flyback supposed to have infinite resistance on the secondary (arc) coil?
Previously, I was able to get nice arcs with the 555 timer and irfp450 MOSFETS. When they died out I thought it was just the FETS but when I went through the proper test procedure for the FETS, I ...

Getting Right parts and building ZVS flyback correctly
I recently built a 555 timer flyback driver. I used 2 IRFP450 MOSFET's in parallel to drive it and I got pretty good arcs. Something always seemed to fail, and I always was buying another 555 chip or ...

Why high voltage from TV flyback shocks you without the need to complete a circuit?
Assuming the TV is plugged into an isolation transformer (although I think there is already a small transformer onboard), then ground is not part of the secondary side. Yet, high voltage from flyback ...

Do I need a flyback diode?
I have some experience using automotive relays and triggering them using the output from a two-way radio aux pin so I am aware of the need to add a diode in parallel with the coil to protect the ...

Flyback diodes issues and pull-in & hold current issues in this Relay circuit
Although this may be a basic question but I'm still struggling with it. In this schematic, two zener diodes D1 and D2 are connected back-to back across relay coil L1. The BVds = -30V for Q1. Can I use ...

Can SPICE simulate inductive device flyback effects?
Following up my earlier question, can SPICE simulate inductive device flyback effects? I would expect so, because this would seem to be a critical part of simulating a switching power supply design. ...
