someone with with YT channel name Contomo (YT- / @contomo5710 ) suggested using a small capacitor in series with the main tank instead of a wire current shunt. Thank you Contomo for this great suggestion!
I made this vid as a quick test using a capacitor shunt instead of a copper wire current shunt. I took some twisted wire and connected it across the 4 uF cap bank. I then connected this to a 10 nF capacitor which reduces the current flowing across the capacitor by 400 times so 400 amps in the main tank becomes 1 amp across the small capacitor. I then put a 40 turn ferrite transformer across one of the legs of the 10 nF capacitor which drops the current from 1 amp to 1/40 amp. With a 56 ohm burden resistor it gives me 1.4V when there is 400A in the tank. This value is a little too small for feedback.
The corresponding output with a 100nF capacitor is 14V so I’m going with the 100 nF which is enough for feedback. When I tried to increase the voltage by using higher value burden resistor such as 1000 ohms, then the corresponding output showed a phase shift. So definitely low resistance such as 10-100 ohm values are necessary! - Наука та технологія
Awesome ⚡️⚡️
Thank you. This will improve the stability of the setup.
@@BrianDhvTinkerer your really nailing this system down, great work!!
