Abstract: A power conversion circuit is provided. According to the topologies of power conversion circuits and the corresponding control manners of the present disclosure, the output voltage is greatly reduced relative to the input voltage, and thus the function of voltage reduction is achieved. Moreover, a voltage-second product of the time and the voltage across the first output inductor and a voltage-second product of the time and the voltage across the second output inductor are both greatly reduced. Accordingly, the inductance, volume and loss of the first output inductor and the second output inductor are greatly reduced. Therefore, the voltage regulation module may receive the low output voltage outputted by the power conversion circuit, thereby reducing the overall volume of the voltage regulation module and increasing the power conversion density and conversion efficiency of the voltage regulation module.
