The charging circuit here uses an ATtiny13A and a MP18021 half-bridge gate driver to charge the capacitor, ... (and doesn’t need to power anything but the PC itself in theory).

The theory, which is the basis for this design idea, is the well-known capacitor-charging equation: V t = V(1 ‒ e ‒t/RC) Time T required to reach a voltage k × V is given by: ...

But line eight of the patent application suggests that the charge storage is much higher than anything achieved in an academic lab: 52 kilowatt-hours in a 2,000 cubic inch capacitor array.

Silicon Mitus released the SM5428, a Switched Capacitor Battery Charger. The DC-DC converter has been highly optimized to meet the demands of the emerging fast charging applications in the USB ...

U1a and U1b act in combination with C2 to form an inverting capacitor charge pump that transfers charge to filter capacitor C3. ... (TINA-TI) allows testing of the theory of a circuit while ...
