Abstract: A power conversion apparatus, a control apparatus, and a switch-mode power supply, which may be used in the field of power supply technologies. A PPC inductor and a switch unit in a PPC circuit are reused in a hold-up time prolonging circuit, so that only at least one capacitor and at least one switch unit need to be added. Therefore, a quantity of newly added components is reduced, and costs are reduced.
