PROJECT DESCRIPTION

The main concept of the project here is to generate a high voltage DC from a single phase AC with the help of the capacitors and diodes connected in a ladder network. This concept is often used in electronic appliances like the CRTs, TV picture tube, and oscilloscope and also in industrial appliances.

 It is also possible to generate up to 10KV DC from this single phase supply, but owing to safety concerns and reasons, this system limits the generating voltage to a 2KV output by limiting the capacitor and diode multiplication factor to about 8.

This project uses a number of silicon diodes and a set of electrolytic capacitors wherein each stage, 2 capacitors are connected in series to withstand the peak voltage. Thus, the output from an 8-stage voltage multiplier can generate up to 2KV.  As a standard multimeter is not possible to measure the output, and therefore, we are using a potential divider of 10:1 for measuring the output such that a 230V low voltage AC reading will get the 2KV high voltage DC.

The project can be implemented by generating a high voltage DC up to the range of 30-50 KV by increasing the number of stages. It can then be used for the required industrial and medical applications.

NOTE: The project needs to be handled with utmost safety, care and precautions as touching any of the high voltage area even a multimeter could be fatal and may result in accidents. The company is not responsible for any such intentional or unintentional consequences.

Q & A
Q:  This project is for 2KV but in multimeter is shown 100V? Why?
A:  The impedance of low cost digital multimeters is approximately 1 M ohm. This can be verified by using a 2nd multimeter in M Ohm (2000K) range to measure the input impedance of the first one while the first one is kept at 1000 v DC volt range. Thus while measuring the voltage across the 1M, another 1M (being the meter impedance) comes in parallel, with a result of effective resistance of 1/2 M or 500K. Therefore the reading seen is half. That is the reason why the displayed value is to be multiplied by 2. However using a very costly multimeter having input impedance of say 100M Ohm shall be showing the correct value as 100M in parallel with 1M will be very near to 1 M only.
Q:  How is 2KV generated?
A:  2KV is generated using capacitors connected in series that add up the voltage up to 2KV.
Q:  Is 2KV measured directly?
A:  No, it cannot be measured directly. However using certain provisions, like using a potential divider, one can measure voltage drop at a particular point..
Q:  Where is it applicable?
A:  It is applicable for electronic appliances like CRT TVs, Oscilloscope and also industrial applications
