Aim To design a switching power supply with multiple outputs used in network analyzer. Methods The technique of PWM(pulse width modulation) is used in Control circuit. The method of switching modulation in series and output filter inductance circle share the same magnetic core. Results The switching power supply with multiple outputs designed in this paper has the characteristic of high efficiency, low ripple voltage and independent multiple outputs each other, meeting the technology demand of the user. It is not only used in network instrument, but also applied to the instrument equipment.
