Abstract
The paper deals with the analysis of accuracy of averaged models of DC-DC converters in the frequency domain. The averaged models of Boost, Buck and Buck-Boost converters are compared with results obtained using the harmonic balance method. It will be shown that the error of averaged models depends on the structure of state matrices and may reach a substantial magnitude even below the Nyquist frequency.
