要約(英語): Analysis precision of boost ratio and power efficiency in boost DC-DC converter circuit is improved by proposing adaptive equivalent circuit of output diode of the circuit. In experiment, boost ratio and power efficiency in high boost ratio circuit were 9.89 and 76.5 percent respectively with its load resistance of 20Ω driven by output voltage 10V. In experimental results, error in theoretical values of boost ratio compared with the measured values of that was reduced to -3.79% from 57.5% in the conventional circuit. In a tapped-inductor high boost ratio circuit, error in theoretical values of boost ratio was reduced to 3.54% from 31.8%. Error in theoretical values of power efficiency with the measured values of that was reduced to 5.51% from 33.2% in the conventional circuit. In a high boost ratio circuit, error in theoretical values of power efficiency was reduced to -3.32% from 17.3%. Power loss of every element in boost DC-DC converter circuits was analyzed with high precision by analysis of inductance current waveforms in those circuits. Error in theoretical values of power loss compared with measured values was reduced to equal or less than 5%.
