Wiring DC Caps For AC Capturing Both Waves

[DMANN]

Ed Cupp did a 3 video series for getting the best charge rate on capacitors using different wiring schemes. This last video shows the best charge rate "capturing both spikes".

He describes hooking up DC capacitors as AC capacitors. Can anyone here describe what is going on? Are the leads simply attached to both ends of the power coil in the SSG circuit? Schematic? Maybe there is another thread that describes this that someone can point me to.

Thanks
