This paper proposes a new method for estimating the capacitance (C) and the value of equivalent series resistor (ESR) of DC-link capacitors for three-phase AC/DC PWM converters. By injecting AC current and extracting the instantaneous and average values of current and
induced AC voltage, the capacitance and ESR can be calulated using resursive least wquares (RLS) method. the estimation error from simulation results error is less than 1%.
