Hello Friends.
As promised , it is my turn to post what I have learned in the last 2 years from you guys.
It is Underunity , because I have a lot more to learn , and I am seeking further advice from you.
I have here :
3 coils in total , 1 trigger and 2 Partenered Output coils
The 2 POC 's are 50 m of magnet wire at 0.7 mm diameter
The trigger is 12 ,5 m of 0.5 insulated wire. ( 1/4 Lenght )
The core is an AMCC 200 from China.
Here they are :
Because I have learned that coil Geormetry plays a strong role in the result , I did not make the Coil Bobbin 10 cm Long , but only 4 cm.
In this situation the coils do not fit one under the other , but One near the Other.
Coil Specs are:
L1 : 12.5 m - 1.2 Ohm - 8.5 mH CW
L2 : 50 m - 2.7 Ohm - 0.26 H CW
L3 : 50 m - 2.7 Ohm - 0.28 H CCW
Experiment Diagram is this :
The scope Shots are this :
Yellow : L1 Gate Voltage
Purple : L1 Current
Blue : L3 Current
Duty : 10 %
DC Bulb around 4 W.
The wire Length's are 1/4 but the turns are not 1/4
The POC have 280-300 Turns
The Trigger has 51 Turns.
The CORE Diameter Alone was small and I could build the 280 Turns , however the L1 is wound on a bigger Surface area , so I could not maintain an Equal Turn Ratio while maintaining the wire length.
I get the desired waveform , but with it or without it , the power Draw from the supply is the same.
The voltage on POC3 is not that great , so only a little bit of current flows.
I did not try to make measurements , because as Chris has said , at an early stage of the experiment , making measurements is pointless.
My experiment is similar to JOHN's his , the only diffrence is that I do not have a Gate Drive at the moment , and the L1 is not made of the same wire Gauge as the other 2 POC.
I would really love to see that "Helping" effect of the POC3 , and any advice to improve the current waveform would be Great.
I apologize if the setting is not very beautiful as yours is , but Investing in a 3D printer for the Bobbins , or an Expensive core , at this early moment of the experiment , as I have so much more to learn , was pointless from my point of view.
Thank you very much for all the hard work and your advice .
