一种新型的具有简易APFC的SPIC电路
A Novel SPIC with a Simple APFC Circuit
摘要
Abstract
A novel SPIC(smart power IC) with a simple APFC(active power factor correction) circuit on one chip is proposed.The Vbus (bus voltage) with high power factor falls from 600V to 400V by using a delay circuit in which a long channel length NMOS is used to substitute a large biasing resistance to save chip area.The lower Vbus results in a smaller Ron(on-resistance) of power switcher,which reduces the power loss of the power devices,improves the efficiency of the circuit,and reduces the cost of circuits.An integrated high voltage over voltage protect circuit is also designed in the circuits.Theory and simulations both prove the correctness and availability of the design.关键词
