A while ago I came up with the idea of using a microwave transformer as a high voltage, high current power supply. Even though I had no use for such a supply, I decided to design one anyway. This is a very simple design mainly to show that there are uncommon uses for common parts. Note: I have not built this supply because I have no use for it. Really it is nothing more then a transformer, rectifier and filter. If you build this supply without knowledge in electronics or high voltage, you have basically signed your own death certificate. This supply can be very dangerous if not treated properly. DO NOT BUILD THIS SUPPLY UNLESS YOU KNOW EXACTLY WHAT YOU ARE DOING! I assume no responsibility for any damages or injuries caused by this supply.

Schematic

Parts

Part	Total Qty.	Description	Substitutions
C1	1	0.68uF 2200V Capacitor
T1	1	2KV Microwave Transformer
S1	1	10 Amp 120VAC Switch
C4	1	2000uf Electrolytic Capacitor
MISC	1	Wire, Line Cord, Output Terminals

Notes

This circuit is dangerous! Do not build it if you do not have any experience with electronics or high voltage.

The circuit can produce about 250-500mA at 2KV, depending on the transformer.

For C1, you can use the capacitor out of an old microwave.

This circuit is mainly provided as a demonstration of using commonly available parts for something uncommon.

can i use this circuit on a jacobs ladder

anonymous High Voltage High Current Power Supply Friday, May 08, 2009 7:36:45 AM

i am a student and power electronices is my fevarite subject( I am looking my carrier in this field ) I designed a 1.5kV, 20WDC power supply from 25 V input as a project. Now I want to learn the different techniques for generating high voltage ( 100kV to 200kV) DC power supply and about the high voltage ferrite core and transformer design. hope you can give me the idea about the circuit thanks.

Its good one. But iwas looking for a circuit 0 to 500VDC variable voltage and 0 to 1000MA variable current circuit. Can you help me in this circuit. Thankyou.

TYKO High Voltage High Current Power Supply Tuesday, March 03, 2009 2:58:38 PM

I need the same power supply, but the purpose of it is to be able to deliver between 5000 and 8000 Amps. How would you modify the circuit?

k i must say ur website is kinda kwl. im a first time user and im definetaly impressed.

Ahmed High Voltage High Current Power Supply Sunday, January 04, 2009 11:48:20 PM

hi i am tecnician of electronics but i need to in crease my cerent of my electriciy when i have 250voltage then i went to saply what i can do thanks if can give me any idea for htat

amalin High Voltage High Current Power Supply Thursday, September 18, 2008 12:24:23 AM

i need to design and construction high voltage DC power supply just like above figure but i don't have any idea to design the circuit. i need to design the circuit that flow 220V and transform 15kV after undergo the transformer. hope you can give me the idea to design this circuit. thanks.

Been using them for years, and yes they will bite you hard. They can be rewound for everyday voltages.

Ive made a HV power supply with a 440ac 60uf Capacitor on the main primary of the transformer: Cap 440vac 60uf Mains(240vac)----------|----------Primary Of Microwave Transformer Mains(240vac)----------|----------Primary Of Microwave Transformer !!!WARNING!!!! VERY DANGEROUS!!! WORKING AT HIGH VOLTAGE AND HIGH AMPERAGE!!! BE CAREFUL OF THE TRANSFORMER IT GETS HOT!!! AND ONLY RUN FOR A SHOT AMOUNT OF TIME!!! You get some pretty amazing sparks, and watch out for x-rays, this operates at a extremely high frequency, i haven't check what frequency it is operating at but i guess close to resonace or maybe even resonance because of the amazing arcs

Xray Man High Voltage High Current Power Supply Friday, May 02, 2008 9:23:12 PM

No, Jimmy... a capacitor from a microwave will not explode if you use it in a DC circuit! Where in the world did you ever get that information from? The only warning that I would give about microwave capacitors is that SOME of them have an internal DIODE manufactured into the same housing as the capacitor. That will usually be shown on the schematic diagram, or noted on the capacitor housing. In that case, you should NOT use that type of capacitor for this circuit.

Hi I am interesting about HVPS ( 15KV ) for Military aircraft . Please let me know if you are interesting to manufacture this product. Please contact with me Thanks Moti

Jimmy High Voltage High Current Power Supply Wednesday, February 27, 2008 12:34:14 PM

CAUTION....CAPS TAKEN FROM A MICROWAVE ARE RATED FOR AC VOLTAGE ONLY...IF YOU INSTALL IT IN A DC CIRCUIT IT WILL EXPLODE..

anonymous A.yusoff High Voltage High Current Power Supply Sunday, January 13, 2008 10:02:28 PM

Yes very intresting project. refer to above schematic dig. the input supply 120vac, 15amp. so the output is 2000V, what is putput amp?. I do a small project i.e. follow sch. dig. but the input is 12vac, 6amp i.e it will be the output 200vac, 100amp. look at the ratio is 16.67 times. pls correct me if iam wrong. pls let me know how produce 12vac,6amp out will be 220-240vac,100amp. Tks.

I need a power supply of some sorts to charge a 2000vdc capacitor. Can you help me out?

such a wonderfull,Interesting and usefull website for electrical and electronics engineers.Also this website should give many new information on High voltage and remotecontrol circuits.HATSOFF to this site.

hameet singh and hemant kamur lun baba da Monday, October 22, 2007 2:08:53 AM

You will need a fuse at switch 1. Make sure you're bridge rectifier (BR1) is rated double the expected voltage (2000V x 1.4=2800V) 6000V would be a good choice. Circuits such as this are used daily by ham radio operaters.Bridge rectifier would have to withstand 2.8KV (peak reverse voltage)! Not easy to find & expensive ...Where is C4 ? What does it do? As an electronics engineer I must caution everyone,don't play with high voltage until you know how to deal with low voltage & then GRADUALLY ! move up to higher stuff. IT WILL KILL !!! Where do you ned C4? Your design of High Voltage High Current Power Supply is really a solution to todays problems

(Editor's notes: Not really, no. It's more of a demonstration of a design exercise. Really it has no use...)

hey whats good this website rocks

That is a good circuit, but the riple it's a true trouble, the capacitor must be so big.
