| 摘要 |
A device for improving power efficiency for power factor correction is disclosed, which comprises a primary load, a power module, a power factor correction module, a current source module, and a secondary load. The power module rectifies an alternating current (AC) voltage to a pulsating direct current (DC) voltage. The power factor correction module filters the pulsating direct current (DC) voltage to a driving voltage. The current source module is connected to the power module, the primary load and a side of the power factor correction module that drives the primary load with the driving voltage. The secondary load is connected to another side of the power factor correction module, and is driven by the power factor correction module. |
