Desktop power active and passive distinction
the power factor can be very high, is helpful to improve the power conversion efficiency, also can make the power supply input voltage is wide
. But the low-end power passive PFC also has obvious shortcomings, the power factor is not high, the input voltage is higher so, now the power of good start using the active PFC,
Desktop power of active and passive refers to the type of PFC, which is the active PFC and passive PFC. passive PFC was formerly very common type, low cost, suitable for the rated power is not high.
