Other Parts Discussed in Thread: TL431
Hi,
I understood the working of the Flyback circuit from the block diagram attached in this mail.
The driver circuit for the Power Mosfet is UC2842A. I understood that this is a PWM controller.
1. How the optoisolator section is helping the driving voltage.
2. I have a design file attached in this thread. For our case F=(1.72/(Rt*Ct)) is coming around 98.85kHz. How the frequency of optoisolator section is affecting in converting the voltage from 240-480V (input) to 24V (output).WBDesign14.pdfWBDesign14.pdf
