A High Voltage Power Supply for your Lab

A High Voltage Power Supply for your Lab Built and Tested by Jean-Louis Naudin Cliquez ici pour la version Franaise created on February 11, 2003 - JLN Labs - Last update February 13, 2003 Toutes les informations et schmas sont publis gratuitement ( freeware ) et sont destins un usage personnel et non commercial All informations and diagrams are published freely (freeware) and are intended for a private use and a non commercial use.

You will find in this document a very useful High Voltage Power supply ( Lab HV-PS ) diagram for your personal laboratory experiments. This is a dual outpout power supply :
- the first output is a Low Voltage output fully tunable between 0 to 70 V DC,
- the second output is a High Voltage output fully tunable between 0 to 30 KV DC

This Lab HV-PS is able to lift off a Lifter v2.0 without problem at a voltage about 21 KV. This allows you to conduct some interesting experiments about the Lifter hovering by tuning the HV output level.

This Lab HV-PS uses common and cheap electronic components that you can buy in any electronic hobby shop.

Note : It is recommend to have one or two BU508D transistors as spare parts, because it is very sensitive to HV pulses.

To build the Lab HV-PS, you may use any common flyback transformer rescued from a old color PC monitor ( see below ).
