I have a simple query
Vin is capacitor charger on DC 350V from AC 230V with circuit breaker 16A.
Q1 - Q4 is full bridge switched for example on 100kHz

What impedance must the Lk and L in transformer current do not exceed 16A?
Which capacitor must be DC blocking capacitor on primary for 16A?
What happens if it is DC clocking C not used?
Assuming R is very low

Raw math starts by using the formula for reactive impedance:

XL = 2 * Pi * f * L

Say you wanted 10A max at 350V. This says you want impedance XL to be 35 ohms. Your spec frequency is 100 kHz. Therefore you solve the above equation for L.

The result is approximate since it does not take into account phase changes, nor does it take into account the secondary side of your circuit.

Nor does it consider the waveform going through the transformer (whether sine wave, square wave, etc.). It is merely a crude calculation via raw math.

You misunderstood the circuit.

Neither "L" nor "Llk" can stop DC current as they are short circuit for DC. You use overcurrent protection to stop at 16A.

The name tells you its function. If you remove it, you lose that function.
