Hello everyone.
Im a noob and i want to learn
I want to build my own efficient fly back driver
I do have a decent understanding of electronic circuits. But i need help with this one. I want to design and build my own zero volt switching driver for a fly back i have. It has an exposed ferrite core that i can manage to wrap seven turns of 14 gauge wire around. My question is how do i calculate the the current draw of the primary side of the transformer at a frequency of around 30khz? at 12 volts. can i use standard inductor calculations or does the core of the transformer or the secondary side of the transformer have an impact on these calculations. What are the effects on the circuit when the transformer is running in its resonant frequency. Afterwords how do i figure out what the best FETs are to use. I have looked at a number of examples of the ZVS circuits, but i do not understand why certain components are placed, where they are in the circuit. I have an example attached.
In the picture i don't understand to purpose of the inductor feeding the primary side of the transformer. Nor do i understand the purpose of the capacitor across the primary. Is it for frequency limitation? And what purpose do the two 400 volt diodes serve?
Thanks. sorry for so many questions. i just want to learn all this.
