I am creating an AC-DC converter circuit that has the following requirements:
Input voltage: 220V / 50 Hz
Output voltage: 200 VDC
Output power: 500W
I use the principle diagram as shown below.
https://ibb.co/q0Bt34K
My transformer uses EE42 core
When the output current is 2.5A, I see the ferrite core is heating up.
I don't understand why this happened, and how to fix it.
My circuit is working at 33 KHz pulse frequency
Please help me
