Webto PWM boost converter is a concern for customers. First, if the boost converter is operated in the continuous–conduction mode (CCM), there is a right half plane zero, which is difficult to be stable. The discontinuous conduction mode is desired for low power application. Second, at light load, boost converter is difficult to regulate because PWM WebOct 11, 2024 · Fig. 2 shows the key operating waveforms of the boost PFC converter operating in DCM.
