Questions
What parts does the ZVS driver with slow start use?
36 parts, built around the OP07 and IRF640NPBF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ZVS driver with slow start KiCad files?
From the GSwitzer/ZVSPCB repository on GitHub, at the commit this page was made from: the board is PCB/ZVS_driver_with_slow_start/ZVS_driver_with_slow_start.kicad_pcb and its schematic PCB/ZVS_driver_with_slow_start/ZVS_driver_with_slow_start.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ZVS driver with slow start design in my own project?
Its repository states no licence, so its author keeps all rights: ask GSwitzer before reusing the design.
