A High Voltage Multiplier Circuit for High Voltage Laboratory, In traditional system high voltage is generated in well-established laboratory where the grounding and other safety concern are well developed. Nevertheless, present status of economic issue and due to lack of skilled staff it very difficult to operate and demonstrate the experiments related to high voltage.It is very useful for, To produce DC voltage up to 10KV using diodes and capacitors,To reduce cost and space,To eliminate heavy equipments.At present, high voltage laboratory are achievement at simply those spaces where financial support are appropriate and ability team are accessible. in spite of of above mentioned issue it is very important to understand the behavior and generation of high voltage theoretically.
