Abstract - The goal of this project is to generate a high DC voltage of approximately 2KV from a 230V AC power source using capacitors and diodes in a ladder network based on the voltage multiplier concept. The method of increasing the voltage is usually done with a phase transformer. The second output of the phase transformer increases the voltage and decreases the current. Another method of increasing the voltage is to double the voltage but from AC to DC. Voltage multipliers are mainly used to produce high voltage when low current is required. This project describes the concept of developing high-voltage direct current (up to 10 kV and more) from single-phase alternating current. For safety reasons, our design limits the multiplier to 8 to keep the output voltage within 2KV. This concept is used in electronics such as cathode ray tubes, cathode ray tubes, oscilloscopes and industrial applications. The circuit design includes a voltage multiplier, the purpose of which is to double the voltage for each stage. Therefore, the 8-phase voltage multiplier can be increased up to 2 kV. Since this cannot be measured with a standard multimeter, a 10:1 divider is used on the output, so that a 200 V reading is 2 kV. Due to the low voltage of the multimeter, the reading is about 7 times the AC input voltage. In addition, the design can be improved to generate a higher DC voltage in the range of 30-50 kV with the number of stages. Then it can be used for industrial and medical purposes.
