Power nguồn Factor Correction (PFC) allows power distribution lớn operate at its maximum efficiency. There are two types of PFC, Active sầu PFC và Passive PFC.....Active sầu PFCThe preferable type of PFC is Active Power Factor Correction (Active PFC) since it provides more efficient power frequency. Because Active PFC uses a circuit to correct power factor, Active PFC is able khổng lồ generate a theoretical power factor of over 95%. Active sầu Power Factor Correction also markedly diminishes total harmonics, automatically corrects for AC đầu vào voltage, and is capable of a full range of input đầu vào voltage. Since Active sầu PFC is the more complex method of nguồn Factor Correction, it is more expensive to produce an Active PFC power supply. Passive PFCThe most common type of PFC is Passive sầu Power Factor Correction (Passive PFC). Passive sầu PFC uses a capacitive filter at the AC input đầu vào lớn correct poor power factor. Passive sầu PFC may be affected when environmental vibration occurs. Passive sầu PFC requries that the AC đầu vào voltage be set manually. Passive sầu PFC also does not use the full energy potential of the AC line.
