WebMay 5, 2024 · (DCM) It is possible to design a flyback converter to operate in continuous current mode (CCM), where the current in the transformer never falls to zero. The design challenge is to ensure you operate always in one mode or another, as getting the control loop stable in a converter that transitions from one mode to another is quite difficult. Webput voltage gain of a DCM flyback converter depends not only on the duty cycle but also on the load condition, which causes the circuit design to be somewhat complicated. How-ever, it is generally accepted that a DCM flyback converter is designed to operate at the boundary of DCM and CCM with minimum input voltage and maximum load as shown in ...
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.
