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.

How can this circuit be modified so it can give high voltage, but low current, something like 400 渙 to 1mA, like that who are used at the electric fences so the animals don't escape?

Can a resistor be placed at the plus output to regulate the current down to some microamps or nanoamps?

i am designing a 3 phase input 4kV/1A dc output power supply what should the rating of my diodes, capacitors and bleeder resistors be?

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.

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.

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

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.
