PROJECT DESCRIPTION

The main concept of this project is to develop a circuit that delivers the output approximately triple  to that of the input voltage by Marx generator principle.It is designed to generate  high-voltage pulses using a number of capacitors in parallel to charge during the on time, and then connected in series to develop a higher voltage during the off period.If the input voltage applied isaround 12v volts DC, then the output voltage is around 36 volts DC.

The proposed system uses a timer in astable mode to deliver the clock pulses, and, a battery for power supply.  This project consists of four stages with each stage made up of a MOSFET, two diodes and a capacitor, respectively – whichare connected to the circuit –wherein  the MOSTFET is used as a switch and the diodes are used to charge the capacitor at each stage without power loss.

This system utilizes a 555 timer in astable mode, which delivers the clock pulses to charge the parallel capacitors during on time and the capacitors are brought in a series during the off time  through MOSFET switches; and thus, develops a voltage approximately triple to the input voltage but little less, instead of exact 36v due to the voltage drop in the circuit. The output voltage can be measured with the help of the multimeter.

This project 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.
