Abstract
A power conversion system includes: first and second switches, a switching power converter, a battery switch and a conversion control circuit. In an external power mode, the first and second switches are controlled to generate an intermediate power from a first power and generate a second power from the intermediate power for powering an external load. In a battery power mode, the conversion control circuit controls the battery switch, the switching power converter and the second switch to generate a system power from a battery power, convert the system power to generate the intermediate power and generate the second power from the intermediate power. In the external power mode, the switching power converter is controlled to enter the battery power mode when the intermediate voltage is reduced to a transient state threshold, wherein a minimum voltage level of the intermediate power is close to a minimum voltage regulation level.
