Saving energy mode (SEM) for an interleaved power factor correction (PFC) converter |
摘要 |
A method of controlling a power factor correction (PFC) converter having a first PFC sub-circuit and a second PFC sub-circuit determines when to transition the PFC converter between an interleaved mode and a saving energy mode (SEM). The method includes generating an amplified error signal based on a monitored output voltage of the PFC converter. The second PFC sub-circuit is disabled in response to the amplified error signal being less than a first threshold value and enabled in response to the amplified error signal exceeding a second threshold value.
