This paper proposes a correction method of capacitance estimation considering the temperature effect for the DC-link capacitor banks
in three-phase AC/DC/AC PWM converters. At first, operating temperature of the capacitors is detected and capacitance variation is
corrected due to the temperature effect. Thermisters are used for sensing the temperature and voltage variation across the thermistor
is exploited to identify the capacitance change. The validity of the proposed method has been verified by experimental results.
