Re: ARSG-BPS required with 2 MOTs?

Hi Wyatt,

You will find that the voltage output drops as you increase the BPS unless
you have an awfully large capacitance in your power supply.  Capacitive
multipliers only charge the output capacitor on every other half cycle
unless you run full wave doublers in which case it is every half cycle which
is still only 100/120Hz.  I run from 100-300BPS because of this using an
ARSG.  I also use inductive charging on the output with a de-quing diode to
double the voltage again.  Currently I get 8.5' arcs to ground.  I have 4
electrodes on the rotary which goes up to 5000rpm.

Best regards,

Paul
