Abstract
A switching power conversion circuit having a two-stage power circuit topology and capable of performing power factor correction is disclosed. In a case that the electrical energy of the switching power conversion circuit needs not to be provided to the system circuit, for example the load and the electronic device fails to be operated, the switching power conversion circuit will be adaptively disabled. As a consequence, the switching power conversion circuit could achieve a power-saving purpose. Moreover, the switching power conversion circuit could be applied to a power supply. When the electronic device is not in use, the power supply has reduced power consumption, thereby achieving a power-saving purpose.
