“…It seems an effective way to suppress the dc bus voltage by keeping both the ICS and the dc/dc converter in DCM for the entire load range [11]- [13], because the dc-bus voltage becomes independent of the load in DCM. Switching frequency modulation methods were reported as alternative to alleviate the dc-bus voltage [14]- [16]. However, the switching frequency could span ten times over the whole load range in order to maintain the dc-bus voltage below 450 V, which is undesirable for the magnetic component design.…”

“…Moreover, harmonic distortions are still significant. On the other hand, operating the dc/dc converter in continuous mode (CCM), at the expense of a larger inductor, is usually more efficient at full load where the current stress is at its maximum and allows the use of frequency modulation to eliminate harmonic distortion of the PFC converter because the CCM dc/dc converter is insensitive to frequency variation [3]. However, in this case, the voltage stress in the storage capacitor varies with the load, and can take a rather high value under low-load conditions.…”
