Zusammenfassung:	A soft-start control for use with a push-pull converter-regulator having a flux balancing circuit. The push-pull converter is responsive to a pulse width modulated waveform to provide a DC output, the converter having an error amplifier for comparing the DC output to a reference signal to vary the duty cycle of the pulse width modulated waveform. The soft-start circuit provides a varying reference signal to the error amplifier, the reference signal gradually increasing from zero to a predetermined level during the start-up of the converter.
