Abstract :
The buck power converter with an LC input filter operating in the discontinuous capacitor voltage mode has inherent power factor correction properties and continuous input current. The paper presents a detailed analysis of the power converter operating in this mode, leading to design criteria. Finally, simulation and experimental results for a 48 VDC/100 W power converter are presented
