Abstract [en]

This project aims to provide understanding the functions of a resistance and capacitance voltage divider and to design one. It is the core principle behind a voltage probe. It should have a bandwidth of 1 MHz, ratio 10:1, τ1 = τ2 and have up to 3 % deviation from the optimal value. Experiments are done to get a better understanding on how the components of the circuit interact with each other. This is done by doing simulations in the software and doing tests in the workshop. Direct current measurements are done to understand how a voltage divider operates and alternate current measurements studies how capacitors in parallel over each resistor in the voltage divider effect the system and therefore the result. It is complicated to design a resistance and capacitance voltage divider since there are many parameters that are in play and impact the result in different ways. Some of the parameters are known and can be calculated and some are parasitic parameters that are more difficult to take in consideration. A more thorough study is needed to find answers on how more of the parameters affect the result. Test number 4 in Appendix 1 exceeds the goal expectation with a bandwidth of 4.24 MHz and a tolerance of 1.2 %.
