         | Isn't that a charge pump? If so, then yes, but it didn't
         | perform well enough to be included.

       | That first circuit makes no sense. DC into a resistor and then a
       | transformer won't do anything but create heat after the core
       | saturates.

         | Yeah, and given that the mistake is consistent between the text
         | and the image, I think the author just sort of doesn't
         | understand inductors.

         | "The efficiency numbers aren't based on calculations or
         | research - I merely ran each circuit in the excellent Lush
         | Projects simulator [SIM] and recorded the numbers it gave me."

         | I don't want to diss people for writing about stuff as they
         | learn, but I wouldn't take this article too seriously. You can
         | theoretically achieve very high efficiency with basic
         | architectures. The main problem is that you typically also want
         | to make the device small and cheap.

         | I think the transformer on it is just supposed to be a 'black
         | box' to show what the other conversions are meant to be filling
         | out

       | If you need higher voltages at modest currents you can consider
       | using one of many voltage doubler circuits after the booster.
       | Just make sure you have enough Ic and simulate it.

       | wehnelt interrupter / electrolytic interrupter can work as a
       | switching up or down converter, fully analog, no transistors,
       | thyristors, no ic, no capacitors, just coil.
       | 
       | single electric motor can be used stationary as a transformer
       | 
       | or in pairs, in motion like inverter, rectifier, (synchronous
       | rotary converter)
