High Step-Up Buck Boost PFC Converter with Active Power Factor Control and Boost PFC Converter

摘要

A multilevel buck-boost (PFC) power factor correction (PFC) converter and boost converter according to the embodiment achieves the same high power factor as when using a separate PFC circuit with only one single element and at the same time, high voltage step-up It makes it possible to obtain a non-output voltage and a negative output voltage.
