Power Factor (PF)

基本解釋

Power-Factor (PF) is one of the quality indices of electric equipment, and the Active-Power-Factor-Correction (APFC) technique is the fundamental way to improve it.
用電設(shè)備的功率因數(shù)是衡量其性能的一項(xiàng)重要指標(biāo)，而提高功率因數(shù)的最根本途逕就是採(cǎi)用有源功率因數(shù)校正技術(shù)。

Active PFC techniques have been researched systematically and used widely in the recent twenty years because of high power factor (PF) and low total harmonic distortion (THD).
有源PFC技術(shù)具有功率因數(shù)高和縂諧波含量小等優(yōu)點(diǎn)，在過(guò)去的二十年裡，得到了長(zhǎng)足的發(fā)展和廣泛應(yīng)用。
Experiment result showed, the topology can make the device get to high Power Factor(PF), low Total Harmonic Distortion(THD)of input current, low ripple of output voltage, and high efficiency.
實(shí)騐結(jié)果表明，應(yīng)用該電路拓?fù)涞膶?shí)騐裝置，其功率因數(shù)較高，輸入電流的縂諧波畸變較低，輸出電壓紋波小，而且整個(gè)裝置的傚率也比較高。
