Expressions for K (D), as well as for the solutions of the de conversion ratios in CCM and DCM, and for the DCM diode conduction duty cycle Dą, are given. The de conversion ratios of the DCM buck, boost, and buck-boost converters are compared in Table 5.2 Summary of CCM-DCM characteristics for the buck, boost, and buck-boost converters Converter Keri (D) DCM MD,K) DCM D (DK) CCM MD) Buck (1 - D) Ô M(D,K) D 1 +V1 +4KID 1+ V1+ 4D’IK Boost ☆ M(D,K) to D(1-D2 M (1 - D2 Buck-boost not to menim laukuri di with K = 2LRT DCM occurs for K <K
