Question: continuous and discontinuous-conduction mode

WebMany pulse width modulate converters can have extra states without a connected path for inductor current. Discontinuous conduction mode (DCM) is easy to control but suffers from high root mean squared (RMS) currents. Converters may operate in continuous and discontinuous conduction modes at different operating points. WebThe Discontinues mode is easier to achieve. Here current is discontinuous, a very high peak current will be present, which requires a large EMI filter and some over sized components. Continuous Mode: Continuous mode usually suits SMPS power levels greater than 300W. helmut barthel twistringenWebYou likely mean “Continuous Current Mode” and “Discontinuous Current Mode”.
