WebJun 15, 2024 · A continuous-conduction-mode (CCM) flyback converter is often used in medium power, isolated applications. CCM operation is characterized by lower peak switching currents, less input and output capacitance, reduced EMI and a narrower operational duty-cycle range than discontinuous-conduction-mode (DCM) operation.
