The project is designed to generate high voltage DC using Marx generator principle by using MOSFET and capacitor stacks. The Marx Principle was developed by Erwin Otto Marx. Its principle is to generate a high voltage pulse using a number of capacitors in parallel to charge up during the on time and then connected in series to develop higher voltage during the off period.

This principle is used to generate voltages in the range of KV’s in real-time for testing the insulation of the electronic appliances like transformers and the insulation of the power carrying lines.

This demo project consists of 4 stages and each stage is made of one MOSFET, two diodes, and one capacitor. MOSFET is used as a switch; diodes are used to charge the capacitor at each stage without power loss. A 555 timer generates pulses for the capacitors to charge in parallel during ON time.

During OFF tine of the pulses the capacitors are brought in series with the help of MOSFET switches. Finally, number of capacitors used in series (4 in our project) adds up the voltage to approximately 3 (4 capacitors-1 capacitor) times the supply voltage.

This system structure gives compactness and easiness to implement the total system from a DC supply of 12V to get approximately (30V-36V).

This concept in future can be extended to Generate High voltages (KV) using more number of capacitors. This technique is adopted for insulation testing of the electronic components, wires, gadgets etc.

Q & A
Q:  What is Marx generation?
A:  Marx generation refers to generation of high voltage by charging a number of parallel connected capacitors and then connecting them in series to add the voltages.
Q:  What is the use of MOSFET?
A:  MOSFET is used as a switch to connect the capacitors in series.
Q:  Is it possible without MOSFET?
A:  No, it is not possible without MOSFET
Q:  What is the use of 555 Timer in this project?
A:  In this project, 555 Timer is used for developing square wave for AC type of feed from DC.

We came to know about edgefx is through searching key words wireless power transfer in google
By seeing the website it so attractive and it is easy to under
with the right components in right time
support team helped me to purchase kit online
develop more projects related to all aspects
i will refer this site to our friends
i will go through your blog

I come to know about Edgefx through Internet while I was browsing for Innovative projects.I found the concept Edgefx site hence I decided to take the kit.I like everything. Yes the kit delivered on time with the right components.Yes Mr. Mohan helped me out while purchasing the project.The Multimeter I got is not working properly.
