Hello,
In the below .pdf Half Bridge schematic, R15 & C3 form a filter to filter out the ringing created by the leakage inductance of the Half Bridge transformer.
Is this the right way to filter out this ringing?
Here is the V(SENSE) waveform, and the primary current of the Half Bridge shown together.

..these two waveforms have slightly different slopes, but should have the same slope, -the difference is presumably due to the slightly varying forward voltage of the rectifier diodes in the sense transformer's secondary, as the current rises during the switching period.
The LTspice sim of the circuit is also attached.
