Abstract
This paper proposes a correction method of capacitance estimation considering the temperature effect for the DC-link capacitor banks in three-phase AC/DC PWM converters. In this work, a sensing circuit using a temperature sensor is designed for measuring the operating temperature. Capacitance value is corrected considering the measured temperature. This method has been implemented in experiment.
