Anyone can learn how to make a Simple High Voltage Generator Circuit and this generator makes a very high frequency power, and this article tell us how to build this type of circuit, as these things are not easy with normal power supply.
One good thing of this high frequency power is that it does not give shock easily if someone touches by mistake it just stays mostly on skin surface.
But still if someone touches circuit directly it can burn and can feel hot.
WARNING: Making high voltage circuit can be dangerous, do this only with expert person watching.
What is a High Voltage Generator Circuit:
High voltage generator circuit is an electronic circuit which make high voltage power, people use this circuit in many things like physics experiment, medical machine, factory work and sometimes hobby projects.
If voltage is more than normal home voltage like 120V or 230V then we call it high voltage.

How to Build:
To make a simple high voltage generator circuit follow the below steps:
- First, connect 555 IC to make simple oscillator.
- Next, use potentiometer and resistors to change frequency.
- Then connect MOSFET with oscillator for correct switching.
- Add filter parts in power supply area.
- Also, connect MOSFET to primary coil winding.
- Then connect output to secondary coil.
- After that, add diodes for one way current and for fix direction.
- Also put inductor and capacitors to clean and smooth the output.
Putting Heat Sink:
- Connect heat sink to MOSFET and this stops it from getting too hot.

Important Formulas for this Circuit:
Transformer Turns Ratio:
Vout = Vin × (Nsecondary / Nprimary)
where:
- Vout is the output voltage
- Vin is the input voltage
- Nsecondary is the number of turns in secondary coil
- Nprimary is the number of turns in primary coil
A high-voltage generator with a transformer uses this formula, as it shows how many times the the wire wounds in the secondary compared to the primary and it shows how much the voltage steps up.
If we add more turns in secondary the output voltage will become more.
Transformer Winding:
Primary Winding:
- Wrap ferrite core with 6 turns of thick insulated wire.
Secondary Winding:
- Put 300 turns of thin wire of 0.4 mm or smaller on solder spool.
- Be sure turns do not go over each other.
Insulation:
- Use plastic strip or insulation between layers with at least 2 layers of insulation till spool edge.
Spacing and Attachment:
- Keep 3 to 4 mm space on each side of winding.
- Use tape so wire do not come near spool edge.
Terminals and Coil Crossings:
- Put wire terminals and crossing in proper way and if winding has 5 layers then keep 120° space between each layer.
- Turn ON the circuit slowly and check if it works good and find its resonance frequency.
- Watch carefully and check the power does not harm other nearby devices and look for anything strange.
Safety Precautions:
- Follow all safety rules when a making circuit.
- Stay away from output to avoid shock or burn.
Conclusion:
To conlude, Simple High Voltage Generator Circuit always think of safety and especially when working with high voltage.
Also, if person does not know much about high voltage circuit then better to ask expert or electronics adviser.
Remember to wear safety gear and follow safety steps every time.
