Bandwidth of Hall sensor?

Simply don't understand your current transformer problem. High frequency CT can be made with single digit nH leakage inductance.

Thanks, but sorry, for this particular problem, its not the leakage inductance which troubles us, its the fact that the magnetising inductance of the CST will be "seen" in series with the LLC's resonant inductor (6uH) , and significantly increase the overall value of the resonant inductance, and we don't want this. We want the magnetising inductance of the CST to be less than 250nH. On a different note, in a different thread, I am indeed concerned about leakage inductance of CST's
 

The magnetizing inductance will be shorted by the secondary shunt resistor (or "burden"), unless you invented a new kind of current sensor.
 

In say a two transistor forward converter, the primary magnetising inductance is not shunted by the load resistor referred to the primary, so why so in the CST?

ok thanks, I see what you mean, and the simulator shows it too....the primary magnetising inductance is indeed shunted by the referred secondary resistance.
