Title: Signs that help in tuning a tesla coil to achieve good resonance more quickly
Post by: VNTC on May 06, 2019, 03:03:17 PM
  The last work leads to the achievement of a tesla coil is tuning. In the process this job if you identify signs that lead to your destination, you will be able to perform this procedure more quickly.
  To see these signs your coil should have a current transformer ratio 1:30 shunt by resistor 1ohm 1W to look them by oscilloscope. This transformer should be a separate one with the transformer in the OCD circuit, because when we hang the probe to this circuit the coil will work not properly.
These signs are:
-      Need to increase primary frequency approx. 10% if our image of  primary current fit image 1
-   Need to decrease primary frequency approx. 10% if your image of primary current fit image 2
-   Just need to make fine tuning few percentages if your image of primary current fit image 3
-   To make step tuning we can adjust C2, C1
-   To make fine tuning we can adjust L1 or the length of discharge wire, keeps its length just right, not too long
