Recently, much attention have been paid to the methods for circuit analysis using wavelet transform. In particular, we have proposed the method which can choose the resolution of the wavelet adaptively. This method can fully bring out the orthogonal and the multiresolution properties of the wavelet, and the efficiency of the calculation can be improved. In this paper, we precisely evaluate the accuracy of the adaptive resolution method to analyze the circuit using wavelet transform by comparing the conventional time marching methods. From the results, we show that the proposed method is suitable for analyses of the power electronics circuits and the hybrid dynamical systems.
