Using an oscillator at a high frequency (around 100kHz) with
a chain of diode/capacitor voltage doublers or a much smaller
transformer than usual.  It is a switched-mode power supply.  If you
look carefully, you can see a transformer on that board, lower right
side, labelled "101".


I'm going to try building something similar but from 1.5V DC up to 150V
AC at 4kHz to power 2' of ElectroLuminescent wire to be self-contained
in a bicycle wheel.
