This work presents a one-switch cross-network boosting power factor correction converter, designed to achieve high voltage gain using a combined switched-capacitor–inductor network with minimal active devices. The hybrid passive network effectively suppresses ripple, reduces interference, and extends device lifespan. Operating principles and conduction modes are analyzed, with comparisons to conventional topologies. MATLAB/Simulink simulations and benchmarking confirm the design, while a 650 W prototype under closed-loop control validates stable operation under variable supply, dynamic load, and sudden disturbances. Results demonstrate fast transient response, near-unity power factor, low THD (1.18%), and a peak efficiency of 97.6%. Overall, the proposed topology advances high-efficiency power conversion and establishes a robust platform for precise regulation and improved power quality in practical applications.
