Leakage flux loss prediction method for conversion system

摘要

Problem to be solved: to provide a leakage flux loss prediction method for a conversion system capable of predicting a leakage flux loss in a conversion system using the result of a single body test in the production of a magnetic element.A method of predicting leakage flux in a conversion system for performing voltage conversion and current regulation;Input voltage of the conversion systemConversion system specific process for converting voltage conversion ratio and frequencyA single inductance assignment process for inputting the inductance value of Coyle unit in the conversion system andA current ripple amplitude value determination process for determining the effective value of the current ripple amplitude value and the current ripple amplitude value of the conversion system;A loss measurement step for measuring losses by using the same effective value as the effective value and the sinusoidal or triangular wave of the same frequency as that of the above described conversion systemThere is a correction step for correcting the loss to the voltage conversion ratio used in the conversion system.Diagram
