    • A power factor correction circuit, a power supply device and a vacuum cleaner using the same. The power supply device for a vacuum cleaner is applicable to a vacuum cleaner having a flexible hose. The power supply device for a vacuum cleaner includes: A power factor correction unit correcting a power factor of an AC voltage supplied from an AC power source; a rectifying unit rectifying the AC voltage power factor-corrected by the power factor correction unit into a direct current (DC) voltage and outputting the DC voltage; a smoothing unit smoothing the DC voltage output from the rectifying unit and outputting the smoothed the DC voltage; an a converting unit converting the smoothed DC voltage from the smoothing unit into an AC voltage, wherein the power factor correction unit uses a conductive line included in the flexible hose, as an inductor.
    • 功率因数校正电路,电源装置和使用其的真空吸尘器。 用于真空吸尘器的电源装置适用于具有柔性软管的真空吸尘器。 用于真空吸尘器的电源装置包括:功率因数校正单元,校正从AC电源提供的AC电压的功率因数; 整流单元,将由功率因数校正单元校正的交流电压功率因数整流为直流(DC)电压,并输出直流电压; 平滑单元,对从整流单元输出的直流电压进行平滑并输出平滑的直流电压; a转换单元,将平滑单元的平滑直流电压转换成AC电压,其中功率因数校正单元使用包括在柔性软管中的导线作为电感器。
