Considerations Behind The Complexity Of Power Factor Correction Device Design

The design of the power factor improvement device not only needs to handle phase adjustment of voltage and current waveforms, but also manage harmonic content and meet regulations and standards under multiple operating conditions. The trade-offs between different topologies are reflected in device size, thermal management requirements, and PCB routing complexity. For some topologies, such as bridgeless totem pole structures, the design phase involves the integration of two independent loops, which places high demands on hardware and firmware development.
