EFFICIENCY EVALUATION TECHNIQUE OF THE SEMICONDUCTOR DC-DC CONVERTER APPLICATION IN THE POWER-SUPPLY SYSTEM

Abstract

Purpose. To specify efficiency evaluation of the DС-DC power semiconductor converter application in the power-supply system. Methodology. We have chosen application version of converter and then used the statistical modeling of DC-DC converter for its efficiency evaluation at varied input voltage according to proposed technique. We have compared the simulated result with the data presented in reference literature. Results. We have proposed the efficiency evaluation technique of converter application. Proposed technique includes detection of external factors influenced on the converter efficiency; development of efficiency evaluation models; selecting application version of converter; determination of the correlation coefficients between the values of external factors; definition of the converter efficiency; obtaining of the converter efficiency distribution. Originality. For the first time, we have developed the evaluation technique of converter efficiency corrected for application version of converter. Practical value. Presented in the study results could be useful for specialists in semiconductor equipment, electrical facilities and systems.
