Abstract :
The accuracy of the averaging approximation is known to deteriorate as the ripple magnitudes of power converters] increase. This paper describes and compares the application of two large-ripple averaging methods, the multi-frequency averaging (MFA) method and Krylov-Bogoliubov-Mitropolsky (KBM) method
