Boost power factor correction converter with adaptive harmonic compensation control

In low-voltage distribution systems, the increased penetration of power electronic devices leads to decentralization harmonic sources, which puts sensitive loads or communication systems in risk status. The conventional methods point-to-point control are not applicable. order solve this problem without increasing additional investments, paper focuses on mitigating interference through factor correction (PFC) converter. Hence, a critical conduction mode (CRM) single-phase boost PFC converter with adaptive compensation (AHC) is proposed reduce at user side. Firstly, feed-forward loop decoupled into fundamental branch and trace generate current. Then gain designed by capacity Meanwhile, characteristics analyzed study effect AHC active transmission output load, can provide important support for method application. Finally, 160-W experimental prototype built verify effectiveness control.
