PROJECT DESCRIPTION

The main objective of this project is to develop a circuit to generate a high-voltage DC from the low-voltage DC by Marx generator principle. It develops an output approximately triple to that of the input voltage by using capacitor and MOSFET combination. If the input voltage applied is around 12v volts DC, then the output voltage is around 36 volts DC.

This demo project consists of 4 stages and each stage is made of one MOSFET, two diodes, and one capacitor. The 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 time of the pulses, the capacitors are brought in series with the help of MOSFET switches. Finally, the 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.
