摘要
Abstract
Input current distortion in the vicinity of input voltage zero crossing of boost single phase power factor corrected (PFC) rectifier in high line frequency occurs. Current loop model and input admittance model of one cycle control PFC boost rectifier is presented. It is pointed that its equivalent power stage of current loop is a 1st order system, and its input admittance is pure resistive in low frequency domain and capacitive since 1 kHz around, then input current phase leads occurs. However, it is does not matter in aero ac power system with 400Hz or 360 ~ 800Hz line frequency,and is suitable for applications as front converter in aero power supply system.关键词
