WebThe ideal current waveform diagram of the CRM flyback converter . Figure 3 is the ideal current waveform of the flyback converter operated in CRM. Assuming that the power factor is 1, the root mean square of the input current can be expressed by the peak value of the average current. Based on the power relation, equation (12) can be derived. ... WebFeb 1, 2024 · The traditional critical conduction mode (CRM) flyback PFC converter with constant on-time control strategy usually suffers low power factor (PF) and high total harmonic distortion (THD) due to the nonsinusoidal input current waveform. In order to solve this problem, an improved variable on-time control strategy for the CRM flyback PFC …
