Hello,
We are doing an 800W Full bridge.
The Current sense transformer has a turns ratio of 400 to 1.
Do you think this is too high a turns ratio and will result in too much interwinding capacitance?
The current sense transformer dissipates 0.441W in its primary due to insertion loss.
800W full bridge spec….
Vin = 18V
Vout = 33V
Iout = 24.2A
Output inductor = 8uH
Fsw (bridge) = 200KHz.
Ns/Np = 2.7
Below is the schematic and LTspice simulation.
