Hello,
The primary magnetising current in this half bridge converter has an envelope of oscillation at 1.39KHz.
The oscillation is obviously between the primary series DC blocking capacitor, (5uF) and the one half of the split secondary (the half that’s not conducting at the time), being referred to the primary [1.62mH * (NS/NP)^2 = 2.62mH ]
Since this oscillation is at such low frequency, how can we damp it out without dissipating too much in the process?
The Half bridge converter is provided here as a PDF schematic, and as an LTspice simulation, and the 1.39KHz oscillation in the magnetising current is also shown.
