If you use a full-wave rectifier, the caps will be charged at
120 times per second. Now, the technique I use has a large
(30,000 uF) capacitor after the rectifier which provides a smooth
DC voltage to start with. The series resistor provides the charging
of the capacitor. Here, the frequency is dependent more on the
EDM process than anything else, but the charging time can be
varied with the resistor value (as well as the combination of
EDM capacitors in the circuit).
