Patent ID: 8310217

Claim:
A power conversion circuit for decentralizing input current, said power conversion circuit generating an output voltage between a first output terminal and a second output terminal, said power conversion circuit comprising: a capacitor connected to said first output terminal and said second output terminal of said power conversion circuit; a first inductor connected to said capacitor; a first switching circuit connected to said first inductor and a common terminal; a first discharging circuit connected to said first inductor, said first switching circuit and said first output terminal; a second inductor connected to said capacitor and said first inductor, wherein said second inductor is connected in parallel with said first inductor; a second switching circuit connected to said second inductor and said common terminal; a second discharging circuit connected to said second inductor, said second switching circuit and said first output terminal; and a control circuit connected to said first switching circuit and said second switching circuit for controlling on/off statuses of said first switching circuit and said second switching circuit, so that said first inductor and said second inductor perform a charging operation or a discharging operation and said power conversion circuit generates said output voltage through said first inductor and said second inductor, wherein under control of said control circuit, said first switching circuit and said second switching circuit are alternately conducted, and said second switching circuit is successively conducted when said first switching circuit is shut off, and said first inductor is connected between said capacitor and an input terminal of said first discharging circuit, and said second inductor is connected between said capacitor and an input terminal of said second discharging circuit.
