A Low Cost Regulated Voltage Doubler Part 2

Walk through the basics of a charge pump circuit. Each components significance is highlighted using a series of slides that show both the schematic and output waveforms. Next, a pulse train is applied to the circuit to create a voltage doubler. Intelligence is later incorporated using a comparator peripheral on a PIC Microcontroller to regulate output voltage. All equations required to build the circuit are discussed as well as derivations and importance. Finally, using the same components, a voltage inverter is created to show some alternate configurations.

Hi, Great video and lots of info. I collect antique radios and am always looking to build "Battery packs" . The old "B" batteries had outputs from 22vdc to 90vdc, using the circuit that you have shown here or something like it, can I build a circuit that will allow me to use a few 9 volt batteries and then devolpe 67 or 90 volts ? I need to concerned about current which is low but still a concern, the plate voltage ..vacuum tubes. Thanks
