Claim 10:
11. The power supply apparatus with step-up and step-down conversion as claimed in claim 1, wherein the step-up converter comprises:
a step-up inductor, a first end of the step-up inductor coupled to the primary-side rectifying/filtering circuit,
a step-up diode, an anode of the step-up diode coupled to a second end of the step-up inductor,
a step-up capacitor, a first end of the step-up capacitor coupled to a cathode of the step-up diode, and a second end of the step-up capacitor coupled to a reference potential, and
a step-up control switch, a first end of the step-up control switch coupled to the second end of the step-up inductor, a second end of the step-up control switch coupled to the reference potential, and a control end of the step-up control switch configured to receive the step-up control signal.
