<p>A soft-start control (54) for use with a push-pull converter-regulator (10) having a flux balancing circuit (48). The push-pull converter (10) is responsive to a pulse with modulated waveform to provide a DC output, the converter having an error amplifier (32) for comparing the DC output to a reference signal to vary the duty cycle of the pulse width modulated waveform. The soft-start circuit (54) provides a varying reference signal to the error amplifier (32), the reference signal gradually increasing from zero to a predetermined level during the start-up of the converter (10).</p> |
