초록
Large aluminium electrolytic capacitors are widely used in inverter systems for smoothing dc-link voltage. If capacitors in dc-link are deteriorated by ageing, dc-link voltage is fluctuated by lessened capacitance and their bodies are heated by raised ESR(equivalent serial resistance) and finally system faults can be occurred. In this paper, on-load ageing test method of electrolytic capacitor in inverter system is proposed and test results are shown.
