Abstract: The project is designed to develop a high voltage DC around 3KV from a supply source of 230V AC using the capacitors and diodes in a ladder network based on voltage multiplier concept. Voltage multiplier are primarily used to develop high voltage where low current is required. this project describe the concept to develop high voltage dc from a single phase ac. For safety reason our project restricted the multiplication factor to 8 such that the output would be within the 3KV This concept of generation is used in electronic appliances like the CRT’s, TV Picture tubes, oscilloscope and also used in industrial applications. The design of the circuit involves voltage multiplier, whose principle is to go on doubling the voltage for each stage. Thus, the output from an 8 stage voltage multiplier can generate up to 3KV. As this is not possible to be measured by a standard multimeter, a potential divider of 10:1 is used at the output such that 200V reading means 2KV. Due to low input impedance of the multimeter, the reading would actually be approximately 7 times the input AC voltage.
