Re: [TCML] Voltage/power dissapation drop across HV DC current limiting resistors.



To all:

Note that you don't have to spray charge in the belts from an active source. The same effect can be obtained by just connecting the lower roller, insulated and made of conductive material, to a relatively high-voltage supply, ald letting the grounded comb do the spraying. In this way practically no current is drawn from the power supply, that can be much simpler. All the energy comes from the movement of the belt. A small electrostatic friction machine can be used, as a small VDG generator using just a rubber band as belt. A small Wimshurst machine made with CD disks can be used to provide bipolar output in this way.
