POWER SUPPLYING APPARATUS AND POWER CHARGING APPARATUS |
摘要 |
There are provided a power supplying apparatus controlling voltage of a power factor correcting circuit according to a power state and a power charging apparatus controlling voltage of a power factor correcting circuit according to a charging state of a battery. The power supplying apparatus includes: a power factor correcting circuit switching input power to correct a power factor thereof and adjusting a voltage level of the power of which the power factor has been corrected according to a state of power transferred to a load; and a resonant DC to DC converting circuit having a resonance frequency varied according to a voltage level of DC power from the power factor correcting circuit and converting the DC power from the power factor correcting circuit into supply power having a preset level according to the resonance frequency.
