ABSTRACT:
A demagnetization circuit for use with a forward converter includes a drive winding magnetically coupled to the primary winding of the forward converter, a capacitor for absorbing leakage and magnetization energies from the primary winding when the forward converter is switched off, an inductor for absorbing energy from the capacitor, and a switching circuit for selectively connecting the inductor to the input voltage source of the forward converter.
