The introduction of silicon carbide (SiC) diodes has been a welcome solution to the reverse recovery losses in continuous conduction mode (CCM) boost power factor corrector (PFC) converters. While SiC ...
Designers have a choice between semi-bridgeless and interleaved PFC pre-regulators. The semi-bridgeless removes half the bridge-rectifier losses, whereas the interleaved PFC can reduce I2R losses up ...
In Part 1 of this article we discussed electric power basics and the need for and advantages of active power factor correction. The next question should be “Okay, then how does active PFC work?” ...
