TIDM-2PHILPFC
概覽
This design is a digitally controlled, two phase interleaved, 700W power factor correction converter with added power metering functionality. A C2000™ Piccolo™ microcontroller is the controller for the two 180° phase shifted boost power stages that comprise the power factor correction converter, and, additionally, it monitors the line and neutral voltage waveforms to implement power metering functions. This design is able to achieve 97% efficiency and 1.5% THD at full load with power factor greater than 0.98. By minimizing power loss in the power stage, reducing reliability impacts of harmonic distortion, and providing near unity power factor, this design is a great choice for off-line applications and AC/DC power supplies.
