1. I wanna know what is the power handling of Siemens EE55 & EE65 cores.

2. As per the circuit given input would be 360V and output +_35V 15A, what should be the min value of input filter Capacitor.

3. I am gonna use 25Khz Swithching Freq using 3525 & i will use 2110 for driving mosfets, Duty Cycle would be 49%, is there any need of filter Choke on output.

4. Selecting Mosfets ??? for 800W.

5. Mosfet voltage 600V .OR. 500V would suffice.

6. Mosfet driver 2110 .OR. 2113

---- EE65 wont handel more than 2.5KW continuos load and may be 4KW peaks at 125KHZ , as per design company recommends. it wont handle the HEAT, UNLESS proper cooling system is there, This is what I can say.
