1. A buck power factor correction system, comprising:
- a first storing device, for storing and discharging energy;
a first converter device, coupled to the first storing device, for transferring and converting energy;
a second storing device, coupled to the first storing device, for storing and discharging energy;
a second converter device, coupled to the second storing device, for transferring and discharging energy;
a rectifying device, coupled to the first storing device, for receiving and rectifying a power source to generate an input voltage; and
a load, coupled to the first storing device;
wherein the first storing device comprises a plurality of energy-storing paths as a plurality of energy-transferring paths; and
wherein the plurality of energy-transferring paths comprise;
a first energy-transferring path, formed by directly charging the first and second storing devices by the input voltage;
a second energy-transferring path, formed by charging the first storing device via the first converter device by the input voltage; and
a third energy-transferring path, formed by charging the first storing device via the second converter device by the second storing device.
