Yes, you are right. I see that as the core is held tighter, the inductance value increases.
I obtained a value of 45uH on the same core. This is still low. The formula says I should get near 60uH, with an AL value of 3700 on the ETD44 without air gap.
What should I use to glue/fix the core...
Thank you schmitt trigger
I am getting these values for 2t+2t primary winding with foil, foil on the inside, secondary outside:
inductance: 32uH,
leakage inductance with all other windings shorted - 8uH
Is this ok?
I am going to wind some more coils differently, to see if I can improve on this...
Thank you mtwieg
My supply rail was ringing, though with a lower amplitude. I am changing the present setup to reduce all possible causes of ringing and ripple, including length of wires and bypass caps.
The switching overlap on the drains seems to happen only on one side of the push pull...
Hi
I am trying to design a dc dc converter with a push pull setup from 12vdc to 340vdc of 1000watts. The frequency of operation is 50khz. For trial and test purposes, I have hand wound - quite tightly - a push pull transformer on an ETD44 bobbin, with a foil of 25mm x 0.05mm x 4 turns with...
Thank you for that, Frank. I am in India, so no insolation issues here, plus the system already has an RTC built in.
Peter, Thank you too. I will look at those current sensors.
Hi
I am looking at designing a solar panel based lead acid battery charger. Say I use a 19VDC panel of 75Watts Peak. I am looking at getting the maximum output from the panel into my battery, so I think I should try to use MPPT in my design. I am going in for either a non-inverting buck-boost...
