摘　　要：非线性载波控制技术是一种近年来发展起来的新型控制技术,其电路是在单周期控制技术中电荷控制基础上外加非线性载波补偿构成的。本文将着重分析非线性载波控制的Flyback电路实现功率因数校正(PowerFactorcorrection,PFC)的方法。首先分析了Flyback电路在连续导通模式(ContinuousConductionMode,CCM)和断续导通模式(DiscontinuousConductionMode,DCM)下的工作原理。该电路结构简单、易实现。仿真和实验表明,该电路稳定性好,功率因数高。Nonlinear-carrier control is a new control technology in recent years.This circuit is composed of adding Nonlinear-carrier compensation in charge control based on one-cycle control.The paper emphases nonlinear-carrier control for Power Factor Correction （PFC） of Flyback circuit.The principle of the circuit working under Continuous Conduction Mode （CCM） and Discontinuous Conduction Mode （DCM） are analyzed firstly,then simulation and experiment are conducted.The circuit is simple and easy to realize.Simulation and experiment verify it has good stability and high Power Factor.
