“…Additionally, when buck-boost converters operate in continuous conduction mode (CCM), the input current is smooth and continuous with very little ripple. The voltage and current stress placed on components by two-switch buck-boost converters is significantly lower than that of single-switch buck-boost converters [22], [42], [53], [81], [87], [97], [102], [103], [115], [117], [119], [125], [133], [138], [142], [146], [164], [168], [222], [225], [263], [264], [266], [288], [289], [308]- [320]. Ahmed et al [315] present a twoswitch non-inverting buck-boost converter with the possibility for extra current storage.…”
