How do you measure the voltage of a cockcroft walton multiplier over time to observe the charging behavior? Does measuring with oscilloscopes discharge the capacitor hence you can't observe the charging or not?
Well, it's a transient, so unless you have a storage CRO or a synchronised camera, you won't see it.shrinky said:Yeah. Ideally I'd like to see the oscillation with amplitude offset increasing as time goes on.
Are you saying it's not working?Right now I have a simple half wave multi stage multiplier set up. I can measure the rectification part, so the sine wave only goes to the positive and not negative, but I don't see the amplitude increase so that the dc offset is always zero essentially.
It shouldn't matter.It could be my driving frequency isn't correct perhaps?
Unless your driving source is floating, you can't connect the CRO across any ungrounded element.Rhetorical I guess but is it better to measure the voltage across the capacitor at the highest stage or measure the potential relative to ground.
A Cockcroft Walton Multiplier is a type of voltage multiplier circuit that uses a series of capacitors and diodes to generate a high DC voltage from a low AC voltage source. The capacitors are charged and discharged in a specific sequence, resulting in a multiplied output voltage.
The charging time of a Cockcroft Walton Multiplier can be measured by using an oscilloscope to monitor the output voltage. The time it takes for the output voltage to reach its maximum value can be used to determine the charging time of the multiplier.
The charging time of a Cockcroft Walton Multiplier can be affected by several factors, including the capacitance and resistance values of the components used, the frequency of the input voltage, and the quality of the diodes.
The charging efficiency of a Cockcroft Walton Multiplier can be improved by using high-quality capacitors and diodes, reducing the resistance in the circuit, and optimizing the frequency of the input voltage. Additionally, ensuring that all components are properly connected and in good condition can also improve charging efficiency.
Yes, the charging time of a Cockcroft Walton Multiplier can be calculated using the formula t = RCln(2N), where t is the charging time, R is the total resistance in the circuit, C is the capacitance of each stage, and N is the number of stages in the multiplier.
