Forward converter transformer saturation prevention










Image Number 17 for United States Patent #8130517.

A power converter in one aspect limits the magnetic flux in a transformer. A control circuit included in the power converter includes a pulse width modulator, logic circuits and saturation prevention circuits. The saturation prevention circuits assert a first signal when a first integral value of the input voltage reaches a first threshold value and assert a second signal after a delay time that begins when a difference between the first integral value and a second integral value of a reset voltage of the transformer falls to a second threshold value. The logic circuits turn off the switch when the first signal is asserted, and allow the switch to turn on and off in accordance with the pulse width modulator when the second signal is asserted.
