Single-phase PFC Adaptive Control Based on Real-time Inductance Identification and Simulink Simulation Verification
摘要
Abstract
To solve the problem of systematic gain mismatch in power factor correction(PFC)circuit caused by nonlinear change of inductance with DC bias,a real-time inductance detection algorithm based on high frequency ripple slope method is proposed.First,a single-phase full-bridge PFC voltage-current double loop control model is established,and the influence of inductance variation on the current loop transfer function is deduced.The current loop bode diagram and simulation results show that the system stability will be affected when the inductance parameters change greatly.Secondly,by monitoring the slope of high frequency ripple current of PFC inductors,the instantaneous inductance value is calculated online,and the PI parameter of current loop is dynamically adjusted at 1 kHz frequency to achieve constant loop gain.The comparison simulation based on Simulink shows that the system can maintain stability un-der large inductance fluctuation under this algorithm.This algorithm can provide a theoretical reference for the design of high reliability PFC circuits.关键词
