Cascade Multiplier |
|
|
|
The circuit for a cascade multiplier is shown below. The circuit is quite simple consisting only of diodes and capacitors. The more stages the multiplier has then the higher the output voltage. All the components should be rated for around twice the input voltage. 1N4007 diodes are rated for 1000v so they should be fine for up to 500v input. The capacitors don't need to have a very large capacitance but they need to have the correct voltage rating. 0.01uF capacitors are a good choice. |

This multiplier was taken from a commercial ioniser designed to be powered directly from the mains 240v supply. It has 21stages and the capacitors are rated 0.022uF 400v. |

I made this multiplier with 0.01uF 630v capacitors. It has 14 stages. |

This multiplier has 12 stages and was made with 1uF 400v capacitors that were bought from a seller on ebay. This cascade multiplier is much larger than any of my others. |

This multiplier has 30 stages. The diodes are 1N4007 1kV types and the capacitors are 0.01uF 2kV types bought from farnell electronics for �0.33 each. |
